How do I solve this prelacy question?

Question Description

I'm doing a finals review and I don't remember this section.
The instructions are: find all solutions of the equation in the interval [0, 2 π)

There are two problems:

4cos(^2)x - 3 = 0

csc(^2)x - cscx = 0

Final Answer

Thank you for the opportunity to help you with your question!

cosx = +-sqrt(3)/2, 

x = pi/6, 11pi/6,   7pi/6, 5pi/6

cscx(csc(x-1)=0 

no solution for csc =0, 

cscx = 1 ---> sinx = 1

x = pi/2 

Please let me know if you need any clarification. I'm always happy to answer your questions.
