How to prove the Law of Sines. Why does the Law of Sines work? In this video we prove the Law of Sines for right triangles. The Law of Sines is a great tool for finding side lengths and angle measures of triangles, so it is good to know...

How do you divide polynomials? This video discusses how to divide polynomials with the box method. I prefer the box method because the standard algorithm for dividing polynomials can be a bit confusing.

How to divide polynomials with a box method when there is a remainder? This video examines how to use the box method for polynomial division when there is a remainder involved. This method is (in my opinion) much easier than the standard...

How can you evaluate an arithmetic series for the first n terms? This video derives the rule/equation, and then includes a few practice problems. We begin by investigating how to the the sum of the first "n" natural numbers, then we...

How can you add up an infinite number of values? In this video we derive the rule and learn how to find the sum of a geometric infinite series. I give a visual example of how we can add up an infinite number of terms in a geometric...

What is a factorial? What is the fundamental counting principle? This video will define these two ideas and provide examples. You will often see these type of problems when figuring out how many ways toppings can go on ice cream or how...

How do you set up distance-rate-time word problems and use a system of equations? This video shows how to use a table to organize information and write the needed equations to solve the system.

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.

This videos shows how to use patty paper for coordinate-plane rotations, explaining the rules for 90°, 180°, and 270° turns and how to apply them to any point.

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.

How do you use the Law of Cosines to find sides (SAS) and find angles (SSS)? In this video, we use the Law of Cosines to find missing sides and angles in oblique triangles.

Learn how to use parametric equations to solve projectile motion problems in this informative and engaging video. We’ll explore the concepts of initial speed, angle of projection, and height above the horizontal to model the path of a...

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

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

This is the first of my videos on factoring polynomials using the box method. Factoring polynomials is never easy, but I've seen several different strategies and I love the box method!

This is the third of my videos on factoring polynomials using the box method. Factoring polynomials is never easy, but I've seen dozens of different strategies and the box method is the BEST

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.

This video explains how to multiply polynomials with the box method. The box method is simply a graphic organizer for multiplying polynomials with distribution

This is the second of two videos on how to factor polynomials using Algebra tiles. It differs from my first video in that this video examines how to use "zero pairs" and negative values.

This video explains how to solve polynomials equations by factoring and using the zero product property

How to simplify when you add, subtract, or multiply radical expressions

In this video, we simplify expressions by using the distributive property and combining like terms.

In this video, we discuss how to simplify expressions with negative and zero exponents.
