can't figure out the second part to either of these

so they just want you to give the answer where theta is 0 to 2pi, because sin(0) is also equal to sin(2pi) which is equal to sin(4pi) etc.
for the first:
2sin(x) = sqrt(3)
sin(x) = sqrt(3) / 2
arcsin(sin(x)) = arcsin(sqrt(3) / 2))
x = pi / 3 (this is something that either needs to be looked up in a table, or using a calculator)
the values of the sin in the first two quandrants are the same, so x = pi/3, 2pi/3

same process repeated for number 2
