e:" (i) "tan^(2)x=3cosec^(2)x-1

tan^(2)x = 3"cosec"^(2)x-1

If: 2.tan^(-1)(cos x) = tan^(-1)(cosec^(2)x) , then: x=

Prove that : (i) tan^(-1) x + cot^(-1)( x+1) = tan^(-1) (x^(2)+x+1) (ii) cot^(-1) 3 + "cosec"^(-1) sqrt(5) = pi/4

Prove that : 2 tan^(-1) (cosec tan^(-1) x - tan cot^(-1) x) = tan^(-1) x

Prove that: tan^(-1)(x)=2tan^(-1)(cosec tan^(-1)x-tan cot^(-1)x)

Prove that : 2 tan^(-1) (cosec tan^(-1) x - tan cot^(-1) x) = tan^(-1) x

If 2 tan ^(-1)(cos x)=tan ^(-1)cosec^(2) x) then x=

The value of 2tan^(-1)(cosec(tan^(-1)x)-tan(cot^(-1)x)) is equal to
