f'(theta)=2cos(2theta)e^sin(2theta)

Explanation,

let's we have u(theta)=e^g(f(theta))

then, using Chain Rule ,

u'(theta)=e^g(f(theta))(g'f(theta))f'(theta)

Similarly differentiating the given function with respect to theta,

f(theta)=e^sin(2theta)

f'(theta)=e^sin(2theta)(cos(2theta))(2)

f'(theta)=2cos(2theta)e^sin(2theta)
