# Differentiate <sp

Let and We need to differentiate u with respect to v that is find .

We have By substituting x = tan θ, we have   Given, –1 < x < 1 x ϵ (–1, 1)

However, x = tan θ

tan θ ϵ (–1, 1)  Hence,  On differentiating u with respect to x, we get  We know and derivative of a constant is 0.  Now, we have On differentiating v with respect to x, we get  We know    We know and derivative of a constant is 0.   We have    Thus, Rate this question :
