This video teaches us to draw the graph of a piecewise function. This is shown using two examples. In the first example we have 'y' equal to 'x + 2' for x less than zero and '1 - x' for x greater than equal to zero. We plot two points on the function for x less than zero and do the same for the function with x greater than equal to zero. The graph for the first function is erased for x greater than equal to zero, and the same is done for the second function for x less than zero. Note that the...
This video shows the method to plot the graph of the absolute value of a function. The video shows the example of the function of cube root of 'x'. The demonstrator first plots the graph of a cube root function. This is done by taking the reference point of positive one and positive eight. The graph is drawn for both negative and positive values of 'x'. After this the graph of absolute function is drawn by taking the absolute value of the cube root function. The resultant graph comes out to b...
In this video the author shows how to plot a point on the coordinate plane. He explains about the coordinate plane and shows how to read and write points to it with an example. He says that any point on the coordinate plane has an x, y- coordinate values. He says that for any point its projection on the x-axis is its x-coordinate and the points projection on y-axis is its y-coordinate. He shows how to find this out for a sample value and plots the coordinates of it. In this video the author u...
In this video tutorial learn how to graph an equation using the slope and y-intercept. To show how this can be done, the equation 4X-5Y=20 is used as an example. The first step that needs to be done is to convert the equation into the y=mx+b format where m is the slope and b is the intersection of the y-intercept. Simply solve the equation for Y and you get Y=4/5X-4. From this, you will find that the slope, or m, is equal to 4/5 and that b is the coordinates 0 and -4. On the graph, you will w...
"Tron: Legacy" may have not been the most plot-driven movie out there, nor will it be an Oscar contender, but cinematography-wise it was truly a feast for the eyes. One of our favorite video game characters from the movie was Gem, one of the sirens who suit Sam up for the games.

This tutorial will show you how to determine the slope of a line if you are given two coordinates on a coordinate plane. You should first find the location of each point on the plane, remembering that the coordinates are in the format of x-axis (or horizontal movement), followed by y-axis (vertical movement). After plotting both these points, you should draw a straight line between these two points and then determine the slope of this line by taking the rise over the run of the line.

Given a function, you can easily find the slope of a tangent line using Microsoft Excel to do the dirty work. That is to say, you can input your x-value, create a couple of formulas, and have Excel calculate the secant value of the tangent slope. This is a fantastic tool for Stewart Calculus sections 2.1 and 2.2.
This video tells you how to draft an equation in point-slope form. Consider the equation (y+4) = 2(x+7) for example. The formula for the point-slope form is (y-y1) = m(x-x1). To plot the graph you have to identify m the slope, the x intercept x1 and the y intercept y1. In this equation the slope is 2 and (x1,y1). The x intercept according to the formula is -x1 but the given value is +7 so you have to figure out what will give you +7,only -(-7) can give you +7 so the point is -7 and now the y ...

The first question asks for the intercepts x and y. To find X, you would need to set Y to zero, leaving the equation 3X=6. X then equals 2 after you divide both sides by 3. The X intercept that you found is not just the value of 2, but it is the ordered pair X=2 and Y=0 on a graph. To find Y, you would do the same thing, except this time X would be set to 0. In the second example of this video tutorial, you will actually learn how to graph the X and Y intercepts. To do that, you follow the st...

This educational math video describes the steps necessary to solve an equation involving absolute values. "Absolute value" refers to the magnitude of a quantity and is always expressed as a positive number. You can think of absolute value as the distance a number would be from zero if plotted on a number line. Positive 17 and negative 17 both have the same absolute value because both are 17 units from zero on a number line. Because of this, all absolute value problems have two answers, one wh...
In this tutorial the instructor shows how to graph a parabola and also how to find its roots which are also known as zeroes. He gives the quadratic formula of how to find x-intercepts of a parabola. He takes an example and substitutes the values and finds out the values of the roots of the parabola. Now he substitutes these values in the equation to obtain the corresponding y coordinates. Now using these pairs of values he plots the parabola on a graph and draws it. This video shows how to fi...
This is an interesting mathematical instructional video on how to make a quartile diagram. This example is about 34 grades obtained by chemistry class students. We need a minimum value, a maximum value, Q1, Q2 and Q3 values to make a quartile diagram. The minimum is 43 and the maximum is 92. To calculate Q2 median formula (n+1 over 2)is used. The Q2 median is 17.5. So the average of 69 and 71 is 70 and hence Q2 70. Similarly Q1 is calculated as 61 and Q3 is calculated as 79. Now you can draw ...
