" 1."cos theta*cosec theta=cot theta

If 6cot theta+2cosec theta=cot theta+5cosec theta , then cos theta is

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

Find cos theta, if 6 cot theta+2 "cosec" theta= cot theta+5 "cosec" theta .

The inverse of [(-cot theta, cosec theta),(cosec theta,-cot theta)] is

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

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

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

Prove the trigonometric identities: sqrt((1-cos theta)/(1+cos theta))=csc theta-cot theta

Prove the following trigonometric identities: sqrt((1-sin theta)/(1+sin theta))=sec theta-tan thetasqrt((1+cos theta)/(1-cos theta))=csc theta+cot theta

Prove the following identity : (sin theta)/(1+cos theta)+ (tan theta)/(1+cos theta)= sec theta cosec theta- cot theta .
