    Why not use alpha plus beta?

    Why not use alpha plus beta?-img_20170328_085209824.jpg

    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.

    FYI: There is a slight point of clarification to the equation here. The dash is not a negative sign.
