" 11."2tan^(-1)(sin x)=tan^(-1)(2sec x)

Solve for x:2tan^(-1)(sin x)=tan^(-1)(2sec x),x!=(pi)/(2)

Solve the following equations : 2tan^(-1) (sin x) = tan^(-1) (2sec x ,) 0 lt x lt pi/2

Solve the following equations: 2 tan^-1(sinx) = tan^-1(2 sec x), x = pi/2

If x in(-1,0), then the function f(x)=2tan^(-1)(cos ecx)+tan^(-1)(2sin x sec^(2)x) may be equal to

2"tan"(tan^(-1)(x)+tan^(-1)(x^3)) ,where x in R-{-1,1}, is equal to

For any real number x ge 1 , the expression sec^(2)x ( tan^(-1)x) - tan^(2)x ( sec^(-1) x) is equal to

2"tan"(tan^(-1)(x)+tan^(-1)(x^3)),w h e r ex in R-{-1,1}, is equal to (2x)/(1-x^2) t(2tan^(-1)x) tan(cot^(-1)(-x)-cot^(-1)(x)) "tan"(2cot^(-1)x)

2"tan"(tan^(-1)(x)+tan^(-1)(x^3)),w h e r ex in R-{-1,1}, is equal to (2x)/(1-x^2) t(2tan^(-1)x) tan(cot^(-1)(-x)-cot^(-1)(x)) "tan"(2cot^(-1)x)
