express 10*sin*w.t in the form A*sin*w.t + B*sin*w.t It is already in the form you want. Just set A = 10 and B = 0.

expres the following as sums and differences of sines or cosines cos8t * sin2t sin(a+b) = sin(a)cos(b) + cos(a)sin(b) replacing by by -b and using that cos(-b)= cos(b) sin(-b)= -sin(b) gives: sin(a-b) = sin(a)cos(b) - cos(a)sin(b) Add the two equations: s...
