Trigonometry begins!

Greetings intrepid mathematical tourists.

We now abandon the algebra highway to turn onto the tortuous and windy way up to the mountain of trigonometry, a particularly precise peak with triangular aspect. In order to more fully acquaint ourselves with the terrain, we’ll be using an online primer (sorry Josie!) that I think does a really nice job of introducing the material gently and completely.

You may want to peruse it over project week if you have some down time and are curious, although it is entirely voluntary.
