In this video, we look at some of the fundamentals of 3D transformations with matrices.

In this video, we briefly introduce the idea of proving that triangles are similar and look at two quick problems.

In this video, we look at the fundamentals for 2D Matrix Transformations.

In this video, we look at the arithmetic, geometric and harmonic means.

In this video, we look at concepts in ratio, proportion and geometric and arithmetic means.

In this video we look at four polar function spirals.

A quick graph of a Lissajous Function. The goal is to write a function that graphs it.

A quick video showing an epicycloid. The goal is to write the function that describes this epicycloid.

A quick video showing a cycloid. The goal is write the function that graphs this cycloid.

In this video, we use desmos to model the average maximum temperature in Tompkins County, NY with a sinusoid function.

In this video, we are solving a fun problem in which we have two points and we need to find the possible locations of the third. All we know is that the three points must form an equilateral triangle.

In this video, we look at some of the instinct as to why Vieta's formulas for the sum and product of roots of polynomials work.

In this video, we will prove that a triangle is isosceles.

In this video we construct the nine point circle, known as Euler's Circle with Geogebra.
