Answer 1

It's great that you want to study hard and succeed!
Please check the Galaxy coaching classes in YouTube..
They upload important question of every chapter and they already did for most of the chapters!
The questions asked by then are highly beneficial and are present in many board exams (previous years)

hope this helps!
cheers! (:

Answer 2

If cosA + cos^2A = 1
TP. sin^12A + 3sin^10A+3sin^8A+sin^6A +2sin^4A+ 2sin^2A - 2 = 1
