Ok, so first part sec((3pi)/4) do you need a decimal or approximate value?

Answer 2

here you go

http://en.wikipedia.org/wiki/Unit_circle#mediaviewer/File:Unit_circle_angles_color.svg

sec = 1/cos
csc = 1/sin

Answer 3

Exact decimal value

Answer 4

The ratio of sec(x) is equal to 1/cos(x) so you need to find cos(x) before you solve for it. Are you allowed to use a calculator?

yes, but I thought sec was hyp/opp???

Answer 6

you're thinking of the cosecant (csc) function. sec is hyp/adj.

use the unit circle, look up cos(135) take reciprocal
look up sin(135) take reciprocal
