Compound Angle Formula Help

Postby grimlock9909 » Fri Mar 04, 2011 1:10 am

Hello, I'm doing a correspondence math course and I'm just having difficulty understanding the steps to take in order to simplify this expression.
sin(pi/4)cos(pi/12)+cos(pi/4)sin(pi/12).

I would suggest that you review your angle-sum and angle-difference identities, and see which might apply.
