Prove the trigonometric identity 1+ cot square A= cosec square A WebDerivative of Cot x. The derivative of cot x is -1 times the square of csc x. Before this, let us recall some facts about cot x. Cot x (cotangent x) in a right-angled triangle is the ratio of the adjacent side of x to the opposite side of x and thus it can be written as (cos x)/ (sin x). We use this in doing the differentiation of cot x.
