There are two values that fulfil $\displaystyle sin\theta=\frac{\sqrt{3}}{2}$

they are $\displaystyle \theta=\:\:, $

second part of the question:

for $\displaystyle sin2\theta=\frac{\sqrt{3}}{2}$ there are 4 values,

if $\displaystyle \theta=\theta_1,\:\:\theta_2,\:\:\theta_3,\:\:\the ta_4$ then

$\displaystyle \theta_3-\theta_1=\theta_4-\theta_2=$

and $\displaystyle \theta_2-\theta_1=\theta_4-\theta_3=$

thanks for any help.
