How to differentiate this $$e^{\tfrac{1}{\sin x}}$$
Help me how to differentiate that please help me Thanks.

Recall the chain rule:
$$\dfrac{d f(g(x))}{dx} = \left.\dfrac{df(y)}{dy} \right\vert_{y=g(x)} \cdot \dfrac{dg(x)}{dx}$$
In your case, $f(y) = e^y$ and $g(x) = \csc(x)$. I trust you know how to differentiate these functions and complete the answer.
