|2019|[2011]2*(sin theta)/(cot theta+cos ec theta)=2+(sin theta)/(cot theta-cos ec theta)

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

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

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

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

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

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

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

sin theta,tan theta,sec thetacos theta,cot theta,cos ec theta1,2,3]|=

If 6cot theta+2cos ec theta=cot theta+5coec theta then cos theta=

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