Answer:

\frac{\mathrm{dy}}{\mathrm{dx}}(\log (\csc x-\cot x))=\csc x

Step-by-step explanation:

Let y = log (cosec x- cot x)

We know that, the general formula for \log x=\frac{1}{x}

Now applying the above formula and differentiating both sides with respect to x, we get

\frac{d y}{d x}=\frac{d y}{d x}[\log (\csc x-\cot x)]

Now, by applying chain differentiation to the above step, we get  

=\frac{1}{\csc x-\cot x}\left[-\csc x . \cot x-\left(-\csc ^{2} x\right)\right]

On simplifying the above step, we get,

=\frac{-\csc x \cot x+\csc ^{2} x}{\csc x-\cot x}

From the above step,  csc x is taken as common in the numerator, we get

=\frac{\csc x(\csc x-\cot x)}{\csc x-\cot x}

\therefore \frac{d y}{d x}=\csc x
