hey here is answer-
to solve this put 1= sec2Q-tan2Q
get p2=sec2Q+tan2Q whole square
p2-1=sec2Q+tan2Q whole square - (sec2Q-tan2Q)
p2+1= sec2Q+tan2Q whole square +(sec2Q-tan2Q)
then p2-1/p2+1 = 2 tan2A + 2secQ tanQ/
2sec2Q+2secQ tanQ
= 2tanQ (tanQ+secQ)/
2secQ (secQ+tanQ)
=tanQ/
secQ
= sinQ hence proved...
hope this will help you
please please mark it as blainliest. .....
