`sqrt((1+cos theta) / (1-cos theta))= (sintheta)/ (1-costheta)`

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

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

root(7)((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))=2cos ec theta

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

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

Prove that : (1-costheta)/(sintheta)+(sintheta)/(1-costheta)=2"cosec "theta

Assertion (A) : ((1+cos theta)/(sintheta))^(2)=(1+cos theta)/(1-cos theta) Reason (R ) : sin^(2)theta = cos^(2) theta-1

int(costheta-cos2theta)/(1-cos theta)d theta=

Prove that : (sintheta)/(1+costheta)+(1+costheta)/(sintheta)=2"cosec"theta
