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

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

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

If cosx = (-1)/2 and pi prec x prec (3 pi)/2 , then the value of 2 tan^2 x+3 cosec^2 x is: यदि cosx = (-1)/2 है तथा pi prec x prec (3 pi)/2 ,है तो 2 tan^2 x+3 cosec^2 x का मान क्या होगा ?

If cosx = (-1)/2 and pi prec x prec (3 pi)/2 , then the value of 2 tan^2 x-3 cosec^2 x is: यदि cosx = (-1)/2 है तथा pi prec x prec (3 pi)/2 ,है तो 2 tan^2 x-3 cosec^2 x का मान ज्ञात करें |

If cosx = (-1)/2 and pi prec x prec (3 pi)/2 , then the value of 4 tan^2 x+3 cosec^2 x is: यदि cosx = (-1)/2 है तथा pi prec x prec (3 pi)/2 ,है तो 4 tan^2 x+3 cosec^2 x का मान क्या होगा ?

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

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

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
