1. The problem statement, all variables and given/known data Solve sin (x + pi/4) = √2 cos x 2. Relevant equations 3. The attempt at a solution sinx*cos(pi/4) + cosx*sin(pi/4) = √2 cos x √2/2 sinx + √2/2 cosx = √2 cos x not sure if im on the right track? or where would I go from here? would I bring √2 cos x to the left side?
