Pupil outcome: I can find the equation of the line in the form y = mx + c Key learning points: - Linear equations can be rearranged into the form y =mx + c. - The gradient and intercept can be identified from the graph. - The equation of...

In this video, we solve rational inequalities by finding critical values and using test points.

In this video, we convert standard form to vertex form, then graph the quadratics.

In this video, we define rational functions and examine how to graph simple rational functions as transformations to the reciprocal function.

In this video, we learn how to restrict domain to find inverse functions.

In this video, we use our background of solving linear systems to solve a nonlinear system.

This is the first of two videos about applications of Periodic Functions. In this video, we examine how to write the equation of a sine or cosine (sometimes called periodic or sinusoidal) graph from a word problem.

In this video, we investigate how to write the equation of a sine or cosine graph when given the an application situation.

How do you write parametric equations when given a table? This video shows how you can use a given table of values to write parametric equations.

How do you type parametric equations into the calculator? In this video, we answer this question by showing step by step instructions (including all the settings) of how to type this kind of relationship into the calculator.

How do you graph secant and cosecant? And, how do these graphs compare to the graphs of sin(x) and cos(x)? In this video, we answer these questions by deriving the graphs for secant and cosecant, and then identifying the domain, range,...

How do you graph y=tan(x) and y=cot(x)? Why do the graphs look the way they do? How do I know where the asymptotes and zeros are for each graph? This video answers all these questions and derives the graphs for these two periodic trig...

How do I graph sin and cos? In this video, we use the unit circle to derive the graphs for sine and cosine. These periodic functions are very similar, but there are some slight differences.

The "b" value controls horizontal stretch and compression. In this video, we examine how changing "b" affects the graph of a function. What does b do to a function? Why is it "backwards?" We explore all of these questions in this video.

Watch this video to find out the basics of writing an equation in point slope form!

Watch this video to learn how to take equations written in standard form and write them in slope intercept form!

This is the first of two videos on solving systems of equations using the substitution method. Make sure to watch "Solving Systems by Substitution 2" for help with solving systems when both equations are in standard form!

This video explains how to use the quadratic formula to solve quadratic equations

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...

In this video, we will dilate figures on the coordinate plane when the center of dilation is not the origin. The first example is a standard dilation (enlargement) with a non-origin center, and the second example gives you both the...

In this video, we examine a problem where we have to use the fact that parabolas are symmetrical in order to solve it.

Find all six trig ratios given a point on the terminal side of theta. In this video we work this common type of problem. We use the Pythagorean Theorem to find "r" (hypotenuse), and then use the given "x" (adjacent) and "y" (opposite) to...
