Question

sec π/5

Answer 1

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?

Answer 2

let me try

Answer 3

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

your problem is exactly the same

Answer 4

-1

Answer 5

that is wrong

Answer 6

how do i solve it?

Answer 7

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

Answer 8

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

Answer 9

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