(cos theta+sin theta)^(2)+(cos theta-sin theta)^(2)=

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

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

Find the A.M. between: ( cos theta + sin theta )^(2) and ( cos theta - sin theta)^(2)

If (cos theta+i sin theta) .(cos 2 theta+i sin 2 theta) ldots ldots(cos m theta+i sin m theta)=1 then the value of theta is

int cos 2theta log ((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

Find the general value of theta which satisfies the equation (cos theta+i sin theta)(cos2 theta+i sin2 theta)......(cos n theta+i sin n theta)=1

If(cos theta+i sin theta)(cos2 theta+i sin2 theta).....(cos n theta+i sin n theta)=1 then the value of theta is:

(sin theta-cos theta)^(2)*(sin theta+cos theta)^(2)=

cos theta+sin theta=cos2 theta+sin2 theta
