SageTex: Trigonometry

Trigonometry using degrees is a little bit easier with Sagetex because with radians Sagetex will take a fraction, such as $latex \frac{3\pi}{4}$ and make it $latex \frac{3}{4}\pi$. That, depending on your personality, can run the range of no big deal to really irritating.

Problem Type 1 (degrees):
