`((sintheta+costheta)/(sintheta-costheta))+((sintheta-costheta)/(sintheta+costheta)) = 2/(1-2costheta^2)`

Prove that : (sintheta-costheta)/(sintheta+costheta)+(sintheta+costheta)/(sintheta-costheta)=(2)/(2sin^(2)theta-1)

If (1+ sintheta-costheta)/(1+ sintheta + costheta)+(1+sintheta+costheta)/(1+sintheta-costheta)= 4 , then which of the following values will be suitable for theta ?

(sintheta)/(1+costheta) + (1+costheta)/(sintheta) = 2 cosec theta

(costheta*csctheta-sintheta*sectheta)/(costheta+sintheta)

If sintheta+costheta=sqrt(2)sintheta , then sintheta-costheta=?

prove that- (sintheta+1-costheta)/(costheta-1+sintheta)=(1+sintheta)/costheta

((1+sintheta+i costheta)/(1+sintheta-i costheta))^n is equal to

If costheta+sintheta=sqrt(2)costheta , then costheta-sintheta is

If sintheta+costheta=x then sintheta-costheta=?
