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

Prove that (1+cos theta)/(1-cos theta)+(1-cos theta)/(1+cos theta)=4cot theta*cos theta

Find the value of sqrt((1+cos theta)/(1-cos theta))+sqrt((1-cos theta)/(1+cos theta))

(sin theta)/(1+cos theta) is equal to (1+cos theta)/(sin theta)(b)(1-cos theta)/(cos theta)(c)(1-cos theta)/(sin theta) (d) (1-sin theta)/(cos theta)

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

(1)/(cos theta)-cos theta =………….

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

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

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

Prove: ((1+sin theta-cos theta)/(1+sin theta+cos theta))^(2)=(1-cos theta)/(1+cos theta)
