Question

Find derivative with respect to x of 2√cot(x^2​​​) ? Please give in detail

Answer 1

As per your doubt, we can see that both answers are the different. But basically, both the answers are the same. In Sinadin's answer,he changed the answer, by converting cosec and cot functions and rearranging them, to make it a function containing sine and cosine functions.

So both the answers are correct and you will get marks for writing any of them. I prefer the method that i chose, because it is simple and not complicated as the 2nd one
