Every point in the unit circle is identified either by its coordinates or by the angle it forms with the x-axis, .
The trigonometric functions associate with every angle and the correspondant coordinates the two values
This procedure can be done for every angle , so you don't have to work with acute angles only.

I tried pretty hard this year, and I think after the exam, I can maintain around a 85-87. I'm just wondering if calculus is a lot more difficult than functions to the people that have already taken both courses.
