Evaluate `sqrt((1-cos theta)/(1+costheta))`

Find the value of sqrt((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))

If pi

If sintheta=(7)/(25) ,then find the value of sqrt((1-costheta)/(1+costheta)) .

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

The value of sqrt((1+costheta)/(1-costheta)) is (a) cottheta-cos e c\ theta (b) cos e c\ theta+cottheta (c) cos e c^2theta+cot^2theta (d) (cottheta+cos e c\ theta)^2

If sintheta=(7)/(25) ,then find the value of sqrt((-1costheta)/(1+costheta)) .

Prove that sqrt((1-costheta)/(1+cos theta))=cosectheta-cottheta .

Prove that : sqrt((1+cos theta)/(1-costheta))=cosec theta+ cot theta .

Prove that sqrt((1+costheta)/(1-costheta))+sqrt((1-cos theta)/(1+cos theta))=2 " cosec"theta.

If pi le theta le (3pi)/2 , then sqrt((1+cos theta)/(1-costheta))+sqrt((1-costheta)/(1+costheta)) is equal to :
