In this video, we factor special product binomials. Specifically, we factor difference of square, sum of cubes, and difference of cubes.

This video discusses how to solve distance rate time word problems with systems of equations. You will often see these types of problems dealing with two different trains, or two different airplanes, traveling in the same or different...

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 learn how to add, subtract, multiply, and divide complex numbers. In the dividing portion of this video (7:05), we look at how to use the complex conjugate to rewrite quotients.

In this video, we explore the relationship between tangent segments and secant segments.

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 learn how to multiply two matrices that are different sizes.

In this video, we define inverse matrices and investigate some of their properties.

In this video, we learn a method for calculating the inverse of a matrix.

In this video, we work examples of exponential growth and decay regarding colonies of bacteria and radioactive decay. We will find the "k" value, and solve for it using logarithms. These exponential word problems are very similar to...

In this video, we do an example of radioactive decay. How do you solve for k? This video shows how to use logarithms (and natural logarithms) to solve for the k or t value. From there, you can use your function to solve word problems.

This video solve word problems with exponential growth (continuous compounding) in finance. We solve problems where we see how long a value takes to double, quadruple, or reach a specified amount.

How to use the Law of Sines to find sides and angles. In this video, we will see how to use the Law of Sines in two practice problems. We will first solve for a side length in a triangle, then we will solve for an angle.

How do we add up the first "n" terms of a geometric sequence/series? In this video, we derive the equation to find the sum of a geometric series. Then, we use that rule to solve a few example problems where we add up the terms in a...

This video explains the connection between the box method and the distributive property when multiplying polynomials. The first example multiplies two binomials, while the second example multiples a trinomial and a binomial.

What is a conditional statement, and how (from that conditional statement) do you create a converse, inverse, and contrapositive?

In this video, you will learn how to solve equations that have fractions by eliminating the fractions first. You will accomplish this by multiplying each side of the equation by the denominator of the fraction you are trying to eliminate

In this video, we will determine if sequences are geometric, and we will find the "r" value (common ratio) for geometric sequences

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 unpack and show the shortcuts to squaring binomials that take the form of (a+b) and (a-b)

In this video, we solve quadratic equations by factoring and using the zero product property. The first example has us factor a quadratic with a leading coefficient of 1, and the second video has us factor a quadratic with a leading...

In this video, we derive the rule for writing geometric sequences using the "n-1" notation.

In this video, we discuss how to multiply terms that have radicals.

Challenges of the Energy Transition in the Global South. This is a clip from the Simba Creative documentary, Without Leaving Anyone Behind.
