Question

Use basic identities to simplify the expression.

Answer 1

what is secant?

Answer 2

reverse of cos

Answer 3

and what is tangent?

Answer 4

@Luigi0210 u there?

Answer 5

yea

Answer 6

secant is the reverse of cosine

Answer 7

and what is tangent?

Answer 8

the reverse of cot i guess

Answer 9

Yes, but it equals something too.

Answer 10

*else

Answer 11

idk

Answer 12

tan = sin/cos

Answer 13

ok so how can this be used to solve this?

Answer 14

Well first you have to change everything to sines and cosines so the new equation is:
(sin/cos)/(1/cos)

Do you know how to switch from division to multiplication?

Answer 15

so it'll be \[(\sin x/ \cos x) \times (\cos x/1)\]

Answer 16

so i should multiply that to get my answer?

Answer 17

Yea, so the cosx's will cancel each other out leaving sinx/1 which is just sinx
