Question

Find one positive and one negative angle coterminal with an angle of
`(11pi)/(8)`.

idk how to do the pi sign

Answer 1

see explanation

Explanation:

Co terminal angles are angle ± 2π, that is

`(11\pi )/(8)` + 2π

=
`(11\pi )/(8)` +
`(16\pi )/(8)` =
`(27\pi )/(8)`

and

`(11\pi )/(8)` - 2π

=
`(11\pi )/(8)` -
`(16\pi )/(8)` = -
`(5\pi )/(8)`
