1. Australopithecus

use the identity to figure it out sin cos tan csc sec cot I just remember SOH CAH TOA, then just write csc under neath to remember the identities so sec(x) = 1/cos(x) know how to solve now?

2. anonymous

let me try

3. Australopithecus

sec(5pi) = 1/cos(5pi) your problem is exactly the same

4. anonymous

-1

5. Australopithecus

that is wrong

6. anonymous

how do i solve it?

7. Australopithecus

sec(pi/5) = 1/cos(pi/5)

8. Australopithecus

$\sec(\pi/5) = \frac{1}{\cos(\pi/5)}$

9. Australopithecus

That is the answer you can easily type it into your calculator to find the answer now
