Question

sec ^ 2 X + cos ^ 2 X + sec ^ 2 x cot ^ 2 X + 1

Answer 1

note that sec x . cotx = cosec x

Answer 2

ok

Answer 3

1 -- cosec^2 x = -- cot^2 x

Answer 4

ok

Answer 5

2sec^2x+cot^2x+cos^2x+1

Answer 6

2sec^2x+cos^2x+cosec^2x
by using formula: 1 - cosec^2 x = - cot^2 x

Answer 7

sec^2x + cos^2x can be broken into (sec x + cosx)^2 - 2

Answer 8

Am not too sure what final simplified form we should be expecting in the question ?

Answer 9

ok.
