Question

Simplify: (2+tan^2x/sec^2x)-1

Answer 1

rewrite the "1" as sec^2/sec^2 , then you can combine fractions

Use identity:
tan^2 = sec^2 - 1

Answer 2

bur what if i change then into sine and cosine?

Answer 3

@dumbcow

Answer 4

yeah you could do that too

it should simplify to

Answer 5

\[2 \cos^2 x + \sin^2 x - 1\]

Answer 6

ok help me that way please :D

Answer 7

use identity:
sin^2 + cos^2 = 1
