(0.05ec theta-cot theta)^(2)=(1-cos theta)/(1+cos theta)

Prove (cos ec theta-cot theta)^(2)=(1-cos theta)/(1+cos theta)

Prove the following identities: (cos ec theta-cot theta)^(2)=(1-cos theta)/(1+cos theta)

To prove (cot theta+cos ec theta)^(2)=(1+cos theta)/(1-cos theta)

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

(sin theta+sec theta)^(2)+(cos theta+cos ec theta)^(2)=(1+sec theta cos ec theta)^(2)

Prove the following identity: cos ec theta(sec theta-1)-cot theta(1-cos theta(1-cot theta)=tan theta-s int h eta

Show that (cos ec theta+cot theta-1)/(cot theta-cos ec theta+1)=(sin theta)/(1-cos theta)

(1)/(cos ec theta-cot theta)-(1)/(sin theta)=(1)/(sin theta)-(1)/(cos ec theta+cot theta)

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

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