Question

Please Help!!!

Answer 1

1+tan^2(x) = sec^2(x) is the identity

Answer 2

See if you can rearrange that to the equation they have

Answer 3

Sec^2(x)=tan^2(x)+1 ?

Answer 4

That's the same thing

Answer 5

isolate tan^2(x)

Answer 6

Oh I thought you meant something else, ok

Answer 7

-1=tan^2(x) ?

Answer 8

what happened to sec^2(x)?

Answer 9

I thought I was supposed to factor it out

Answer 10

No you're just moving 1 to the other side of the equation

Answer 11

oh ok

Answer 12

What would this give you?

Answer 13

tan^2(x)=sec^2(x)-1

Answer 14

yep. So is the answer true or false?

Answer 15

True

Answer 16

Good job

Answer 17

Thank you
