please help me with some questions I skipped on a review for our test coming up?

solve 5-7 on the interval 0 greater than or equal to x less than or equal to 2pi.

5. sin x=sqrt3/2

6. cos x=-1/2

7. tan x=0

----------------

14. what is the exact value of tan[arcsin(.43)]?

----------------

15-16 find an algebraic expression equivalent to..

15. cos(tan^-1 x)

16. cot(arcsin x)

----------------

solve then describe all solutions

17. tan x-sqrt3=0

18. 2sin x+sqrt3=0

19. 2cos x+sqrt2=0

20. sinx cosx=0

Thank you soo much for any help!
