i) `(costheta-sintheta)/(costheta+sintheta)=tan(pi/4-theta)=cot(pi/4+theta)=sqrt((1-sin2theta)/(1+sin2theta))`
ii) `(costheta+sintheta)/(costheta-sintheta)=tan(pi/4+theta)=cot(pi/4-theta)=sqrt((1+sin2theta)/(1-sin2theta))`

Text Solution

Verified by Experts

The correct Answer is:
(i)`= tan (pi/4 -theta)` (ii) `cot (pi/4 +theta)`
