Learn How To Find Derivative Of Cot X Using Quotient Rule Of Differentiation

Derivative of cot x

-csc^2 x

The derivative of cot x can be found by using the quotient rule of differentiation.

We know that cot x = cos x/sin x.

Using the quotient rule, we get:

(d/dx) (cos x/sin x) = [(sin x)(-sin x) – (cos x)(cos x)] / (sin x)^2

Simplifying the numerator, we get:

-dx/dx = -1

Therefore, the derivative of cot x is -csc^2 x.
