[AASL][AAHL] Trigonometric relationships (Unit Test v2.2)

Hey y'all.

This unit test is long overdue; I just couldn't find the inspiration to write a decent unit test on trig relationships. The SL version will be uploaded soon; it's mostly identical to the HL paper, maybe one fewer question and lower "grade boundaries".

Enjoy!
