If tany = (2t)/(1-t^2) and sin x = (2t)/(1+t^2) then (dy)/(dx) =_____

sinx = (2t)/(1+t^(2)), tan y = (2t)/(1-t^(2))

If sin x=(2t)/(1+t^(2)),tan y=(2t)/(1-t^(2)), find (dy)/(dx)

If sin x = (2t)/(1+t^(2)), tan y = (2t)/(1-t^(2)) , then (dy)/(dx) is equal to

If sin x=(2t)/(1+t^(2)),tan y=(2t)/(1-t^(2)),quad find (dy)/(dx)

Find (dy)/(dx) of each of the functions expressed in parametric form: sin x= (2t)/(1 + t^(2)), tan y= (2t)/(1-t^(2)), t in R

Find the derivatives of the following : x=(1-t^(2))/(1+t^(2)), y=(2t)/(1+t^(2))

If tan x = (2t)/(1 -t^(2)) " and sin y" = (2t)/(1 + t^(2)) , then the value of (dy)/(dx) is
