1. The problem statement, all variables and given/known data Let f(x) = sqrt(sin(e^(x^4*sinx))) Find f '(x) I tried this many times and it's really frustrating! I made it a composition function : f(g(h(x))) but I'm not getting the answer at all. At the end, I found : 1/2(sin(e^((x^4)(sinx))))^(-1/2) (cos(e^(x^4 sinx))) (e^(x^4 sinx)) (4x^3 cosx) But it's wrong. Could someone please tell me where I went wrong or how to solve this please.
