# Math Help - Finding a reference angle and a trig function

1. ## Finding a reference angle and a trig function

$tan(315^0) = -1$ Find the reference angle and trigonometric functions for cosecant0 and secant0

I think this has something to do with the 4 quadrants on the graph, but I forget how to apply it to this question. Thanks!

the reference triangle for $\theta = 315^\circ$ is a 45-45-90 triangle in quadrant IV ... hypotenuse = 1 , adjacent and opposite sides = $\frac{1}{\sqrt{2}}$
