Coordinates in 3-Space

This post was inspired by a calculus student¬†and will be in three¬†parts: This on the development of different coordinate systems, one with calculus and one without. We are taught in school that the volume of a sphere with radius is . In this post we shall look at a development in calculus that will not […]

An Interesting Trig Circle

We are going to go through a (light) development of some trig identities by using geometry. We will not get into specifics or prove these claims in this post. There might be a post later to prove these statements. So without further ado let’s start with a circle. Choose two points on the circle that […]
