How was Absolute Zero discovered? Where does it come from?
Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0. The theoretical temperature is determined by extrapolating the ideal gas law; by international agreement, absolute zero is taken as −273.15° on the Celsius scale (International System of Units), which equates to −459.67° on the Fahrenheit scale (United States customary units).The corresponding Kelvin and Rankine temperature scales set their zero points at absolute zero by definition.
It is commonly thought of as the lowest temperature possible, but it is not the lowest enthalpy state possible, because all real substances begin to depart from the ideal gas when cooled as they approach the change of state to liquid, and then to solid; and the sum of the enthalpy of vaporization (gas to liquid) and enthalpy of fusion (liquid to solid) exceeds the ideal gas's change in enthalpy to absolute zero. In the quantum-mechanical description, matter (solid) at absolute zero is in its ground state, the point of lowest internal energy.
The laws of thermodynamics dictate that absolute zero cannot be reached using only thermodynamic means, as the temperature of the substance being cooled approaches the temperature of the cooling agent asymptotically. A system at absolute zero still possesses quantum mechanical zero-point energy, the energy of its ground state at absolute zero. The kinetic energy of the ground state cannot be removed.
Scientists have achieved temperatures extremely close to absolute zero, where matter exhibits quantum effects such as superconductivity and superfluidity.
One of the first to discuss the possibility of an absolute minimal temperature was Robert Boyle. His 1665 New Experiments and Observations touching Cold, articulated the dispute known as the primum frigidum. The concept was well known among naturalists of the time. Some contended an absolute minimum temperature occurred within earth (as one of the four so-called "elements"), others within water, others air, and some more recently within nitre. But all of them seemed to agree that, "There is some body or other that is of its own nature supremely cold and by participation of which all other bodies obtain that quality."
The question whether there is a limit to the degree of coldness possible, and, if so, where the zero must be placed, was first addressed by the French physicist Guillaume Amontons in 1702, in connection with his improvements in the air-thermometer. In his instrument, temperatures were indicated by the height at which a column of mercury was sustained by a certain mass of air, the volume, or "spring", of which varied with the heat to which it was exposed. Amontons therefore argued that the zero of his thermometer would be that temperature at which the spring of the air in it was reduced to nothing. On the scale he used, the boiling-point of water was marked at +73 and the melting-point of ice at 51, so that the zero of his scale was equivalent to about −240 on the Celsius scale.
This close approximation to the modern value of −273.15 °C for the zero of the air-thermometer was further improved upon in 1779 by Johann Heinrich Lambert, who observed that −270 °C might be regarded as absolute cold.
Values of this order for the absolute zero were not, however, universally accepted about this period. Pierre-Simon Laplace and Antoine Lavoisier, in their 1780 treatise on heat, arrived at values ranging from 1,500 to 3,000 below the freezing-point of water, and thought that in any case it must be at least 600 below. John Dalton in his Chemical Philosophy gave ten calculations of this value, and finally adopted −3000 °C as the natural zero of temperature.
After James Prescott Joule had determined the mechanical equivalent of heat, Lord Kelvin approached the question from an entirely different point of view, and in 1848 devised a scale of absolute temperature which was independent of the properties of any particular substance and was based on Carnot's theory of the Motive Power of Heat. It followed from the principles on which this scale was constructed that its zero was placed at −273.15 °C, at almost precisely the same point as the zero of the air-thermometer.

Learn how to determine the extrema from a graph. The extrema of a function are the critical points or the turning points of the function. They are the points where the graph changes from increasing to decreasing or vice versa. They are the points where the graph turnes. The points where the graph changes from increasing to decreasing are called the maximum point while the points where the graph changes from decreasing to increasing are called the minimum point.

MIT grad shows how to find any limit as x approaches a finite value/constant value (and not infinity). To skip ahead: 1) For an example of PLUGGING IN/SUBSTITUTION, skip to time 1:45. 2) For FACTORING to simplify, skip to 3:53. 3) For GETTING A COMMON DENOMINATOR, skip to time 8:09. 4) For EXPANDING by opening up parentheses to simplify and find the limit, skip to 12:01. Nancy formerly of MathBFF explains the steps.
Jump to the PART 2 video (https://youtu.be/v9fQ_QeCHpI) for how to find the limit for: 5) a SQUARE ROOT in the numerator or denominator (to RATIONALIZE by multiplying by the "CONJUGATE"); 6) something of the form (SIN X)/X; or 7) an ABSOLUTE VALUE in the limit expression.
For LIMITS at INFINITY, jump to: https://youtu.be/nViVR1rImUE

1) TRY PLUGGING IN/SUBSTITUTION: The first way to try to find the limit value is to plug in for x. In the limit expression, x is approaching a certain number. If you plug in this number and get a value that is defined, then that is your limit. HOWEVER, if you get ZERO in the denominator when you plug in, then you have not found the limit yet and need to try something else to find the limit value.
2) TRY FACTORING: If you plugged in the value for x, and you got zero in the denominator (or the form 0 over 0), check whether you can factor and simplify to find the limit. If the limit expression is made up of a polynomial in a numerator and a polynomial in the denominator, then it is a very good idea to try factoring because a factor in the top may cancel with a factor in the bottom to give you a simpler expression. Then, plugging into this simpler expression may give you an actual limit value.
3) TRY GETTING A COMMON DENOMINATOR: If you plugged in the value for x, and you got zero in the denominator, and you cannot factor the expression, you have to try something else. If your limit expression has fractions within a fraction ("a complex rational expression"), try getting a common denominator in the expression. Use algebra to get a common denominator between the two fractions that are in the numerator (or denominator), and when simplifying, terms may cancel so that you have a simpler expression you can plug into to get a limit value.
4) TRY EXPANDING/OPENING UP PARENTHESES: Again, if you plugged in and got a zero in the denominator, and you can't factor or get a common denominator, consider opening up parentheses and expanding expressions by FOIL-ing or multiplying out and combining like terms. Simplifying in this way may lead to a simpler expression you can plug into to get a limit value.

This calculus video tutorial explains how to identify points of discontinuity or to prove a function is continuous / discontinuous at a point by using the 3 step continuity test. This involves evaluating piecewise functions using one sided limits. The first step is to determine if the function is defined at the given point. The second step is to prove that the limit exists by showing that the right side equals the left side. If the limit does not exist, it could be a jump discontinuity or an infinite discontinuity which are nonremovable. The 3rd step is to show that the limit equals the function at the given point. If the limit exists but does not equal the function, then it's a point discontinuity also known as a hole which is removable.

Quickly master how to find the quadratic functions for given parabolas. Watch more lessons like this and try our practice at https://www.studypug.com/algebra-help/quadratic-functions/find-the-quadratic-functions-for-given-parabolas
In the last lesson, we learned how to draw a parabola from its function. This lesson, we will do the opposite. We will learn how to find the quadratic function when we are given the graph of a parabola.
Here we are given a parabola with the vertex at negative 1 and 4. Vertex. The question explicitly tells us the information for the vertex, that means we should use the vertex form to model this parabola, right. Makes sense? Yeah. So let's use the vertex form to model this parabola. Okay? Let's go. So vertex form goes something like this, right, with y on the left side of the equation, x on the right side of the equation with the square right here meaning we are dealing with a quadratic function, right, cool. And the a here is the leading coefficient for the parabola, okay? Cool. Now, vertex. So this vertex information should be able to tell us the information about something here, and something here, right? So let's go. For this vertex the x coordinate is negative 1. So if you want to make the statement look something like this, with a bracket and the x inside, we are looking for a value here, right? Would you say that means we have to move the number to the same side as x, and we can put a bracket around the statement, right? So let's do this. Now, negative 1 is moved to the other side of the equation, it becomes positive 1, right? And now the rest of the equation we just have zero, and now we can put a bracket around this whole thing. And that is gonna be the information we are gonna put down here, right, yeah. So inside the bracket what do we see? X plus 1. So inside the bracket, we just put down x plus 1. And that's done, okay? So the x portion is done. Now let's take care of the y portion. So for the vertex, the y coordinate is 4. Let's do the same thing, move the number to the same side as y. So positive 4 moved to the other side becomes negative 4, and this side of the equation we just have zero. And now, we can put a bracket around this, right. And now we can put this whole thing right here. So inside the bracket we have y minus 4. Inside the bracket we have y minus 4. And now this portion of the equation is done. So now how do you determine the value for the leading coefficient? Well there's still one information we haven't used, so chances are this will help us find a leading coefficient: the information about this point. So let's go. What does this point tell us? What information can we get out of this point? Well, this point is basically telling us that for this quadratic function, when x equals negative 3, the corresponding y value is 12. And guess what? These other values will plug into the equation to find the leading coefficient. Okay? So here, x value, we're going to plug in negative 3. Here, the y value, we're gonna plug in 12. Okay guys? And let's try to solve for a. So left side of the equation we have 12 minus 4, we get-- let me use another color. So, left side of the equation we have 12 minus 4 we get 8 .equals, a is the value we are trying to find. Now, this side we have negative 3 plus 1, we have negative 2. And don't forget outside we gotta have a square, right. Cool. Now, a equals negative 2 squared. Guys, negative 2 squared we get positive, right. Positive of what, 2 squared is 4. So we have 4a. Okay guys. Now, to solve the value for a, to solve the value for a, we simply divide both sides of the equation by 4. That way 4, 4 cancels out. So at the end, a equals 8 divided by 4 is 2. That's it, that's the value for a right here. Okay, guys? So at the end, for this parabola, the quadratic function is right here, okay? Left side of the equation we have y minus 4 equals. . . Guys, what's the value for a right here? A is 2, right? So a is 2. So we put it in right here. Now bracket, inside the bracket we have x plus 1.

This algebra 2 and precalculus video tutorial explains how to determine whether a function f is even, odd, or neither algebraically and using graphs. This video contains plenty of examples and practice problems using variables and constants. First, plug in -x into the equation and see if the sign changes. If all signs change, it's an odd function. If they all remain the same, then it's an even function. If some change while others do not, the function is neither even or odd. For graphs, even functions are symmetric about the y axis. For odd functions, the symmetry exists about the origin. For circles with even and odd properties, it does not pass the vertical line test and is therefore not a function.

In this lesson, we will discuss the very important topic of p-values in statistics. The p-value is a calculation that we make during hypothesis testing to determine if we reject the null hypothesis or fail to reject it.
The p-value is calculated by first finding the z test statistic. Once this is known we then need to find the probability of our population having a value more extreme than the test statistic. This is done by looking up the probability in a normal distribution table. We then interpret the results by comparing the p-value to the level of significance.

Learn about graphing absolute value equations. An absolute value equation is an equation having the absolute value sign and the value of the equation is always positive. The graph of the parent function of an absolute value equation is a v-shaped graph starting from the origin above the x-axis and rising both sides of the y-axis and is symmetrical to the y-axis.
To graph an absolute value equation, we first graph the parent function of the absolute value equation and we then apply the necessary transformation(s) to the graph of the parent function to obtain the required graph of the absolute value equation.

http://www.freemathvideos.com In this video playlist I will show you the basics for polynomial functions. We will start with factoring polynomial equations to determine the zeros of a polynomial. We will then learn how to write the polynomial given a set of zeros. Multiplying, adding and subtracting polynomials will be apart of this series as well as classifying polynomials and determining the Leading coefficient and degree of a polynomial so that we can determine the end behavior. Next we will learn how to find all of the zeros of a polynomial using the rational zero test and descartes rule of signs. This will help us apply the factor and remainder theorem. We will also learn how to sketch the graph of a parabola using the multiplicity and zeros.

Learn how to graph linear inequalities written in standard form. Linear inequalities are graphed the same way as linear equations, the only difference being that one side of the line that satisfies the inequality is shaded. Also broken line (dashes) is used when the linear inequality is 'excluded' (when less than or greater than is used) and a solid line is used when the inequality is 'included' (when greater than or equal to OR less than or equal to is used).
To graph a linear inequality written in standard form, we first determine the slope and the y-intercept by rewriting the linear inequality in slope intercept form, we then plot the y-intercept and using the slope, we can determine the rise and the run of the required line and then be able to plot the next point from the y-intercept. We then draw a straight line passing through the two plotted points.
Alternatively, we can determine the x-intercept and the y-intercept of the standard form linear inequality by subtituting y = 0, then solve for x and substituting x = 0, then solve for y respectively. Recall that the x-intercept is the value of x when y = 0 and the y-intercept is the value of y when x = 0. After obtaining the values of the x-intercept and the y-intercept, we plot the points on the coordinate plane and then draw a line passing through the points.
After the line representing the linear equation form of the linear inequality is drawn, we select a point either side of the line to determine which side of the line is true for the given inequality and then shade the side that satisfies the inequality.

I turn most limits into split (piecewise) functions when dealing with absolute values. That lets me evaluate the limit with other methods (like factoring) from the left and the right, so see if the double-sided limit exists.

This video covers how to make a relative frequency distribution chart. Remember that in a relative frequency distribution we scale back the frequency using the total frequency. Depending on rounding, the total relative frequency might not be one, but should be very close. For more videos please visit http://www.mysecretmathtutor.com
