I ran into this trig identity trying to do my physics hw:
a*cos(s)+b*cos(t)
I tried deriving it using an analogous approach to deriving the product-sum trig identity, but ran into problems. I was wondering if this trig identity exists, or if I should just try to find some clever way to solve the physics problem without the trig identity.
