Question

Prove that the left side equals the right side.

1 + sec^2x sin^2x = sec^2x

Answer 1

is it sin2x or sin^2x?

Answer 2

1+sin^2x/cos^2x
=1+tan^2x
=sec ^2x

Answer 3

OK wow that's good. HOw did you get the 1/cos^2? Is that the reciprocal of sec^2?

Answer 4

yes

Answer 5

Awesome thanks!

Answer 6

yes...secx=1/cosx
so sec^2x=1/cos^2x

Answer 7

Oh i'm sorry i chose the wrong best answer. Thanks anyways jdoe
