The WildTrig playlist gives a simplified introduction to Geometry via Rational Trigonometry. It will also present a wide range of applications. It is meant for good high school students, undergrad math majors, engineers, scientists and just those with an interest in geometry.
The MathFoundations playlist presents a simple way to set up modern mathematics on a rigorous foundation. It starts from the very beginning, without reliance on unsubstantiated `axiomatic systems' or other voodoo. It will also show how mathematics education can benefit by understanding mathematics in a natural way.
There is also a third channel that consists of mathematical seminars I have given. These are more advanced, aimed for math major undergraduates and graduate students, along with fellow mathematicians.

We define acute and obtuse triangles, and give inequalities for acuteness in terms of the spreads of the triangle. Then we look at the circumcenter...

The three spreads of a triangle satisfy the Triple spread formula, and given two such spreads this gives a quadratic equation for the third. The Tr...

Added visual approach combined with remarkable lecturing style makes these videos very good learning resource. Once again, thank you very much.
It is in the application that the real difference comes out. I cannot emphasize enough: move from abstract contemplation to actual solving of real life practical problems, and rational trigonometry wins hands down.
I have a question. Your Rational Trig series, can it "replace" the original trignometry completly? What I mean is, I will make a test on trig soon, if I use rational trig, will I get burned by the teachers? Do people know about this?
Just asking, for safety reasons.
