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

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

Prove the following identities: (sin theta)/(1-cos theta)+(tan theta)/(1+cos theta)=sec theta cos ect+cot theta

(tan theta)/(1-cot theta)+(cot theta)/(1-tan theta)=1+sec theta*cos ec theta

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

Prove that: ((1)/(cos theta)-(1)/(sin theta))(1+(sin theta)/(cos theta)+(cos theta)/(sin theta))=sec theta tan theta-cosec theta cot theta

(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=2cos ec theta

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

(tan theta)/(sec theta-1)-(sin theta)/(1+cos theta)=2cot theta

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

(sin theta-cos theta + 1) / (sin theta + cos theta-1) = sec theta + tan theta
