Best ResponseYou've already chosen the best response.0Do you have a unit circle ? it is just asking for what values of x is sin 1/2 sin(x)=1/2

Best ResponseYou've already chosen the best response.0\(\bf y=sin(x)\qquad \begin{array}{llll} (x&\frac{1}{2})\\ \uparrow&\uparrow \\ x&y \end{array}\implies \frac{1}{2}=sin(x) \\ \quad \\ sin^{1}\left( \cfrac{1}{2} \right)=sin^{1}[sin(x)]\implies sin^{1}\left( \cfrac{1}{2} \right)=x\)

Best ResponseYou've already chosen the best response.0so, find that angle, and any other angle with the same value in the range of \(\left[ 4\pi ,\frac{\pi }{2} \right]\)
