Step-by-step explanation:
√(1+cos theta)
(1- cos theta)
=✓(1+cos theta)*(1+cos theta)
(1-cos theta) (1+cos theta)
=√ (1+cos theta)^2
(1-cos theta^2)
= √(1+ cos theta)^2/sin theta^2
= (1+ cos theta)/sin theta
= 1 + cos theta ( 1/sin theta= cosec theta
sin theta sin theta. cos theta/sin theta= cot theta)
= cosec theta + cot theta
