i dont know how to start this problem. i dont like cos and sin. im so confuse.

1.f(x)=sin(sin(x)), find f'(x)

2.f(x)= 4sin^4x, find f'(x). this problem i couldnt find it in my math book. i never see it before. because of sin exponent 4 -->sin^4

cos(sin(x))*cos(x)

16sin^3(x)*cos(x)

d/dx(f(x))= f'(x)*x'
