Question

use the given values to evaluate (if possible) all six trig functions: cos (pi/2 - x) and cosx = 12/13

Answer 1

Is this the question as it appears in your text?

Could you post a screen shot of the problem?

Something seems to be missing.

Answer 2

^^ @Daisyblake11

Answer 3

yes that's how it is

Answer 4

one sec

Answer 5

>>cos (pi/2 - x) Is this complete?

Answer 6

lol it isn't. my bad

Answer 7

cosx = 12/13 is partially helpful but we do not know whether we are in quadrant III or quadrant I.

If you post a screen shot of the problem, I may be able to help. Otherwise, I cannot.

Answer 8

it's cos(pi/2-x) = 5/13 and cos x = 12/13

Answer 9

cos (pi/2 - x) = sin x = 5/13

So far, we have:

cos x = 12/13

sin x = 5/13

That leaves:

sec x
csc x
tan x
cot x

Answer 10

@Daisyblake11 Do you know the reciprocals of the trig functions?

Answer 11

yes i do. thank yo so much

Answer 12

Good to know.

What is this equal: sec x =

Answer 13

13/12

Answer 14

csc x =

Answer 15

13/5

Answer 16

tan x =

Answer 17

sinx/cosx

Answer 18

Right. Substitute the values we already have for sin x and cos x into the tangent fraction and crank out the numerical value of the tangent.

Answer 19

got it

Answer 20

5/12

Answer 21

cot x =

Answer 22

12/5

Answer 23

We have them all. Good work.

Answer 24

thank you. good work :)

Answer 25

You are welcome.
