" If "sin t+cos t=(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 x=a(cos t+(log tan)(1)/(2)),y=a sin t then (dy)/(dx) is equal to

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

If (1+sin t)(1+cos t)=(5)/(4) then find the value of (1-sin t)(1-cos t)
