Hi there I'm currently stuck on one of the questions from my math assignment... I'm hoping some kind and smart souls on the Internet can help me with it. Here's the question.
Rewrite 3 cos(x) - 4 sin(x) as r cos(x + alpha ), where r > 0 and alpha (0, pi/2).
(hint, cos(a + b) = cos(a) cos(b) - sin(a) sin(b))
