Alright so here is my problem, first day of college started I am in Calculus and have never took a trigonometry class in my life. Because Calculus involves some trigonometry the teacher assigned us a trig review for homework and I have no clue on how to do it, thanks for the help I get.

Here are some of the problems:

Provide all EXACT solutions for the variable on the interval [0,2pie)

2sin3pie/4 = X

2cos(x) = -1

3sec(7pieX/3) = -2(square root of 3)

if you could explain how u got the answers I would appreciate it thank you
