Question

differentiation of sin squarex divide by 1 plus cos square x

Answer 1

Hey!!!

Here is your answer__________

let,

y = (sin^2 x)/(1 + cos^2 x)

we know,

(1+cos^2 x) = sin^2 x -------[ first trigonometric identity]

y = (sin^2 x)/(sin^2 x)

y = 1

by differentiating y with respect to x we get,

dy/dx = 0
