" (i) "(cos theta+sin theta)/(cos theta-sin theta)

int cos2 theta * ln ((cos theta + sin theta) / (cos theta-sin theta)) d theta

Evaluate: int cos2 theta ln((cos theta+sin theta)/(cos theta-sin theta))d theta

int cos2 theta log((cos theta+sin theta)/(cos theta-sin theta))=

If tan theta=(a)/(b) then find the value of (cos theta+sin theta)/(cos theta-sin theta)

If b tan theta = a find the value of (cos theta + sin theta )/( cos theta - sin theta)

If (cos theta+sin theta)/(cos theta- sin theta)=8 , then the value of cot theta is equal to: यदि (cos theta+sin theta)/(cos theta- sin theta)=8 है, तो cot theta का मान किसके बराबर होगा ?

cos theta+sin theta=cos2 theta+sin2 theta

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

Prove that (cos theta-sin theta)/(cos theta+sin theta)=sec2theta-tan2theta

Prove that :(cos theta-sin theta)/(cos theta+sin theta)=sec2 theta-tan2 theta
