In this video, we examine how to solve absolute value inequalities by representing the inequalities on a number line.

In this video, we learn how to add, subtract, multiply, and divide function values from multiple representations.

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

In this video, we investigate how to find the determinants of 2x2 and 3x3 matrices.

In this video, we define and use sigma notation for series.

In this video, we use sigma notation to evaluate series.

How do you plot points in the complex plane? How do you find modulus of a complex number? This video answers these questions by graphing points on the complex plane, defining modulus (absolute value), and calculating modulus.

How can you tell if a relation is a function?

Watch this video for basic definitions and applications of that Algebra ideas of domain and range.

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...
