If `sin t + cost=1/5` then `tan(t/2)` is equal to:

Suppose o lt t lt (pi)/(2) and sin t + cos t =1/5 then tan "" t/2 is equal to

If sin t+cos t=(1)/(5) then tan((t)/(2)) is equal to:

Suppose 0 lt t lt pi/2 and sint+cost=1/5 . Then, tan""t/2 is equal to :a)2 b)3 c) 1/3 d)5

If x = sin t and y = tan t , then (dy)/(dx) is equal to a) cos ^(2) t b) (1)/( cos ^(3) t ) c) (1)/( cos ^(2) t ) d) sin ^(2) t

If tan(theta/2)=t then (1-t^2)/(1+t^2) is equal to

If t+1/t =5, then (2t)/(3t^(2)-5t+3) is equal to ……..

If tan theta=thentan2theta+sec2 theta is equal to (1+t)/(1-t)(b)(1-t)/(1+t)(c)(2t)/(1-t)(d)(2t)/(1+t)

If tan theta=t , then sin 2theta is equal to :

If b lt 1. sin t lt0.cos t lt 0 and log_(b) (sin t)=x, then log_(b) (cost) is equal to
