Evaluate: `int1/xsqrt((1-sqrt(x))/(1+sqrt(x))dx)`

Text Solution

Verified by Experts

`I=int 1/x sqrt((1-sqrtx)/(1+sqrtx))dx`
Put `x=cos^2 theta` `dx=-2sin theta cos theta d theta`
`I=1/cos^2thetasqrt((1-cos theta)/(1+cos theta))(-2sin theta cos theta)d theta`
`I= int ((-2 sin theta)/cos theta)sqrt((1-cos theta)/(1+cos theta)) d theta` ...
