Why are they using sin(alpha)+sin(beta) instead of alpha+beta?

Hey abhistud. Hint - If something is a solution then it means that x = alpha and x = beta should give zero on LHS for both equations. Also note - sin^2(x) + cos^2(x) = 1 and use other trig identities to simplify things.

Thanks for that.
