(sin A cos B +cos A sin B) the whole square + (cos A cos B- sin A sin B) the whole square.
A=60
sin A =sqrt%283%29%2F2
cos A = 1%2F2
B=30
Cos B = sqrt%283%29%2F2
Sin B = 1/2

%28%283%2F4%29%2B%281%2F4%29%29%5E2+%28%28sqrt%283%29%2F4%29%2B%28sqrt%283%29%2F4%29%29%5E2

%281%29%5E2%2B%28%282sqrt%283%29%29%2F4%29%5E2
