Question

find the derivative of f(x)= sin2x​

Answer 1

Answer:2cos2x

Step-by-step explanation:

Given,

f(x)=sin2x

Let, f(x)=sin2x=y

It's derivative is

dy/dx = d(sin2x)/dx

= cos2x.d(2x)/dx

Since, derivative of sinx is cosxd(x)/dx = cosx

dy/dx = 2cos2x

Hence,

The derivative of sin2x is cos2x
