" these wifter ":(1+cos theta)/(sqrt(1-cos theta))=cosec theta+cot theta=cos^(6)(theta)/(2)

sqrt((1+cos theta)/(1-cos theta))=csc theta+cot theta

( 1 + cos theta) ( 1 - cos theta ) cosec^2 theta =

sqrt((1-cos theta)/(1+cos theta))=cosec theta-cot theta (Prove It)

csc theta(1+cos theta)(csc theta-cot theta)=1

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

prove that (1-cos theta)/(1+cos theta)=(csc theta-cot theta)^(2)

Prove that ((1+cos theta)/(1-cos theta))=("cosec"theta + "cot"theta)^(2)

The value of (1+ cos theta)(1- cos theta) "cosec"^(2) theta =

(sqrt((cosec^(2)theta-1)))/(cosec theta)=cos theta

If pi lt theta lt 2pi then sqrt ((1+cos theta)/(1-cos theta))= a. cosec theta+cot theta , b. cosec theta - cot theta , c. cot theta-cosec theta , d. -cosectheta - cot theta
