If `alpha+beta=pi/2 and beta+gamma=alpha` then `tan alpha` equals (A) `2(tanbeta+tangamma)` (B) `tanbeta+tangamma` (C) `tanbeta+2tangamma` (D) `2tanbeta+tangamma`

If alpha+beta=(pi)/(2) and beta+gamma=alpha then tan alpha equals (A) 2(tan beta+tan gamma)(B)tan beta+tan alpha (C) tan beta+2tan gamma(D)2tan beta+tan gamma

If alpha+beta=(pi)/(2) and beta+gamma=alpha then tan a equals-

If alpha+beta=(pi)/(2) and beta+gamma=alpha, then find the value of tan alpha.

Let alpha,betaa n dgamma be some angles in the first quadrant satisfying tan(alpha+beta)=(15)/8a n dcos e cgamma=(17)/8, then which of the following hold(s) good? (a) alpha+beta+gamma=pi (b)cotalpha+tanbeta+tangamma=tanalphatanbetatangamma (c)tanalpha+tanbeta+tangamma=tanalphatanbetatangamma (d)tanalphatanbeta+tanbetatangamma+tangammatanalpha=1

If 2sinalphacosbetasingamma= sinbetasin(alpha+gamma) then tanalpha, tanbeta & tangamma are in

If tanalpha+tanbeta+tangamma=tanalphatanbetatangamma,then

If alpha+beta+gamma=2pi , then show that tan.alpha/2 + tan.beta/2 + tan.gamma/2 = tan.alpha/2 tan.beta/2 tan.gamma/2 .

If alpha+beta+gamma=2pi, then (a) tan(alpha/2)+tan(beta/2)+tan(gamma/2)=tan(alpha/2)tan(beta/2)tan(gamma/2) (b)tan(alpha/2)tan(beta/2)+tan(beta/2)tan(gamma/2)+tan(gamma/2)tan(alpha/2)=1 (c)tan(alpha/2)+tan(beta/2)+tan(gamma/2)=-tan(alpha/2)tan(beta/2)tan(gamma/2) (d)none of these
