Solve for x : 2tan^(-1)(sinx)=tan^(-1)(2...

Solve for `x :` `2tan^(-1)(sinx)=tan^(-1)(2secx),\ x!=pi/2`

Text Solution

Verified by Experts

`2tan^(-1)(sinx)=tan^(-1)(2secx)`
According to the question,
`tan^(−1)((2sinx)/((1−sin^2x)​))=tan^(−1)(2secx)`
`=> (2sinx)/(1−sin^2x)​=2/(cosx)`
`=> (sinx)/(cos^2x)​=1/(cosx)​`
