Spherical Trigonometry - An Introduction and Basic Theorems

This video is an introduction to spherical trigonometry. I give the basic concepts and derive the spherical version of the Law of Cosines and Law of Sines. Examples of how to use each are given in the context of solving spherical triangles. You can see more of my math videos at www.math4every1.info .

Hello, I found your video extremely helpful, as I am doing a small research work on spherical geometry. I was just wondering, what program/application did you use to create the visual models of spheres and figures generally speaking you used for this video?

Glad you found this helpful. I develop software for a 3D solid modeling package called ZWCad. I used this package to create most of the images.
