Evaluate `((1-tantheta)/(1-cottheta))^2`

((1-tantheta)/(1-cottheta))^(2)+1=

Prove that : (tantheta)/(1-cottheta)+(cottheta)/(1-tantheta)=1+sectheta" cosec "theta

What is the value of (sintheta)/(1-cottheta)-(cos theta)/(1-tantheta) ?

Prove that (1+tantheta)^(2)+(1+cottheta)^(2)=(sectheta+"cosec "theta)^(2) .

i) Prove that: (1+tan^(2)A)/(1-tan^(2)A) xx (2 cos^(2) A-1)=1 ii) Prove that: (tantheta)/(1+cottheta)+(cottheta)/(1+tantheta) = "cosec"theta.sectheta-1

Find the value of ((1)/(costheta)+(1)/(cottheta))((1)/(costheta)-(1)/(cottheta)) .

The value of (2cos^(2)theta-1)((1+tantheta)/(1-tantheta)+(1-tantheta)/(1+tantheta)) is

If sintheta=(3)/(5) , then the value of (tantheta+costheta)/(cottheta+cosectheta) is equal to

If sectheta+tantheta=5 , then the value of (tantheta+1)/(tantheta-1) is
