I assume that's sin (.5A). There is a half-angle formula for sin.
so can you please help me solve the problem?

\[\cos^2A+\sin^2A=1\]\[\cos A=\sqrt{1-\sin^2A}\] From this \(\cos A\) can be found u can find \(\cos A\). Then use \[\cos A=1-2\sin^2(\frac{ 1 }{ 2 }A)\]\[\sin \frac{ 1 }{ 2 }A=\sqrt{\frac{ 1-\cos A }{ 2 }}\] from this u can find \[\sin \frac{ 1 }{2}A\] Does that help?
but do u have an answer?
Mine is at the very top
did u use the half-angle formula because i'm getting a radical?
what r u getting?
|dw:1364228079352:dw||dw:1364228136955:dw| |dw:1364228182827:dw|
getting it?
is that the complete answer?
ok thank you so much
Welcome:) do u get it?
yes :)
