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

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

(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

prove that (cos theta)/(1-tan theta)+(sin theta)/(1-cot theta)=cos theta+sin theta

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

((sec theta+tan theta)(1-sin theta))/ (cosec theta(1+cos theta)(cosec theta-cot theta)) is equal to: ((sec theta+tan theta)(1-sin theta))/ (cosec theta(1+cos theta)(cosec theta-cot theta)) का मान किसके बराबर है?

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

cos ect theta(sec theta-1)-cot theta(1-cos theta)=tan theta-sin theta

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