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

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

int(cos ec theta-cot theta)/(cos ec theta+cot theta)dth eta

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

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

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

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

(cos theta)/(cos ec theta+1)+(cos theta)/(cos ec theta-1)=2tan theta

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

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)

Which of the following is not equal to (cot theta+cos ec theta-1)/(cot theta-cos ec theta+1)?
