Solve the following equation for `x`: `tan^(-1)((2x)/(1-x^2))+cot^(-1)((1-x^2)/(2x))=(2pi)/3,x >0`

Text Solution

Verified by Experts

`cot^(-1)(1/x)=tan^(-1)x`
`tan^(-1)(2x/(1-x^2))+tan^(-1)(2x/(1-x^2))=(2pi/3)`
`2tan^(-1)(2x/(1-x^2))=(2pi/3)`
`2tan^(-1)x=(pi/3)`
`tan^(-1)x=(pi/6)`
`x=tan(pi/6)=>(1/(sqrt3))`
