Evaluate: `int({e^(sin^(-1) x)}^2)/(sqrt(1-x^2))dx`

Text Solution

Verified by Experts

`cos y = xcos(a+y)`
Differentiating both sides w.r.t. `x`,
`-sinydy/dx = cos(a+y)(1)+x(-sin(a+y)dy/dx)`
`=>dy/dx(xsin(a+y) - siny) = cos(a+y)`
As, `cos y = xcos(a+y) => x = cosy/cos(a+y)`
`:. dy/dx(cosysin(a+y) - sinycos(a+y)) = cos^2(a+y)`
