y = sin(log( ecosx)) exponentil​

Answer 1

Answer,let sin=u,log=v and ecosx=w

From w Dy/dx ecosx=cosxecosx ,let this =w

Frm V,Dy/dx logw =1/w therefore 1/cosxecosx let this=v

From u, dy/dxsin v= cosv

Therefore we have cos(1/cosxecosx) as the final answer.

But there are other longer methods to solve this which would involve the use of product or logarithmic rule.
