I assume that's sin (.5A). There is a halfangle formula for sin.

\[\cos^2A+\sin^2A=1\]\[\cos A=\sqrt{1\sin^2A}\] From this \(\cos A\) can be found u can find \(\cos A\). Then use \[\cos A=12\sin^2(\frac{ 1 }{ 2 }A)\]\[\sin \frac{ 1 }{ 2 }A=\sqrt{\frac{ 1\cos A }{ 2 }}\] from this u can find \[\sin \frac{ 1 }{2}A\] Does that help?
