Aim: How do we find the cosine of the difference and sum of two angles?

Aim: How do we find the cosine of the difference and sum of two angles?. If m A = 35º and m B = 20º show which of the following identities is true?. Do Now:. cos(A – B) = cos A – cos B. cos(35º – 20º) = cos 35º – cos 20º. cos(15º) = .8191520443 – .9396926208. .9659258263 = -.1205405765.
