If `tan(alpha+beta)=sqrt3` and `tanalpha=1/sqrt3` then `tanbeta=`
`(A) 1/6`
`(B) 1/7`
`(C) 1/sqrt3`
`(D) 7/6`

if tan(alpha+beta)=(1)/(2) and tanalpha=(1)/(3), then tanbeta =______.

tan_(tan6 beta)(alpha+beta)=sqrt(3),tan(alpha-beta)=1 then

tan^(-1) (1/(sqrt3))

If tan(A+B)=sqrt3 and tan A = 1, then tan(A-B) is equal to

If tan alpha = sqrt(3) and tan beta = (1)/(sqrt(3)) , then find the value of cot (alpha + beta) .

If alpha +beta = 90^@ and alpha:beta = 2 : 1 , then tanalpha : tanbeta is equal to (A) 1 : 3 (B) 2 : 3 (c ) 3 : 2 (D) 3 : 1

If tanalpha =(1)/(7) and tanbeta =(1)/(3) , then, cos2alpha is equal to

If tanalpha=(1)/(7)&tanbeta=(1)/(3) , then cos2alpha=?

If alpha and beta are acute angles satisfying cos2 alpha=(3cos2 beta-1)/(3-cos2 beta), then tan alpha=sqrt(2)tan beta (b) (1)/(sqrt(2))tan beta(c)sqrt(2)cot beta(d)(1)/(sqrt(2))cot beta

Let alpha and beta be nonzero real numbers such that 2(cosbeta?cosalpha)+cosalpha cosbeta =1 . Then which of the following is/are true? (a) sqrt 3 tan(alpha/2)+tan(beta/2)=0 (b) sqrt3 tan(alpha/2)?tan(beta/2)=0 (c) tan(alpha/2)+sqrt3tan(beta/2)=0 (d) tan(alpha/2)?sqrt 3tan(beta/2)=0
