Answer: e^{\sin x} \cos x+(\tan x)^{x} \cdot\left[\log (\tan x)+\frac{x \sec ^{2} x}{\tan x}\right]

Hint: Diff by e^{\sin x}

Given: e^{\sin x}+(\tan x)^{x}

Solution:  y=e^{\sin x}+(\tan x)^{x}

Let   z=(\tan x)^{x}

Take log on both sides

        \log z=x \log \tan x

Diff w.r.t x

        \frac{1}{z} \frac{d z}{d x}=\log \tan x+\frac{x \sec ^{2} x}{\tan x}

Thus

        \frac{d y}{d x}=e^{\sin x} \cos x+(\tan x)^{x} \cdot\left[\log (\tan x)+\frac{x \sec ^{2} x}{\tan x}\right]
