    Rational Trigonometry

    There is an Australian math professor on youtube.com named NJ Wildberger teaching entire math courses for free online. One of the courses is titled Rational Trigonometry.

    I do not recall learning trigonometry the way he teaches the class. It is very intense and complex. What on earth is Rational Trigonometry? What makes it different from the "regular" trig we all learned in high school?
