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

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

The value of sec theta((1+ sin theta)/(cos theta) + (cos theta)/(1+sin theta))- 2 tan^2 theta is

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

A simplified of ((Sin theta)/(1+cos theta)+(1+cos theta)/(sin theta))(1/(tan theta+cot theta)) is: ((Sin theta)/(1+cos theta)+(1+cos theta)/(sin theta))(1/(tan theta+cot theta)) का सरलीकृत मान ज्ञात करें |

" 4."(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=(2)/(sin theta)

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

(sin theta)/(1-cot theta)+(cos theta)/(1-tan theta)=(a)theta(b)1(c)cos theta-sin theta(d)cos theta+sin theta

Prove that (1)/(2){(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)}=(1)/(sin theta)

1-(sin^(2)theta)/(1+cos theta)+(1+cos theta)/(sin theta)-(sin theta)/(1-cos theta) equals
