find:
sin 23pi/12
i got totally the wrong answer how do i approach this?

That is pi/12 less than 2 pi (360 degrees), which would be 345 or 15 degrees. The sin of that angle is 0.2588
If you don't want the decimal approximation, it is
sin(45  30) = sin 45 cos 30 + sin 30 cos 45 = (sqrt 2)/2*[1/2  (sqrt3)/2]
= (sqrt2)/4 (sqrt6)/4 
haha i got that too! but the right answer is
(root(2root(3)))/2 
why don't you evaluate your "right" answer and compare it with drwls answer ?
MMMhhh ??
