Step-by-step explanation:
cosec theta + cot theta = P (given)
we know, cosec² theta - cot² theta = 1
(cosec theta + cot theta)( cosec theta - cot theta)= 1
(cosec theta - cot theta) × P = 1
( cosec theta - cot theta) = 1/P
Let's solve (i ) and (ii)
cosec theta = 1+ P²/2P cot theta = P²-1/2P cot theta / cosec theta= P²-1/2P×2P/P2²+1 cos theta = P²-1/P²+1
