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!
