Solve the equation please

Question

sin x = 0.5 on

[0,2π)

(-infinity,infinity)

Answer 1

hi,

sin x = 0.5 = 1/2

x = 30 , 150 or ∏/6 and 5∏/6 these answers belong to the (0,2∏)

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

x = 2k∏ + ∏/6

x = 2k∏ + 5∏/6

you choose k = { ...., -2,-1,0,1,2,....} and find all answers in ( -∞ , +∞ )

I hope it is useful,
