    Finding a reference angle and a trig function

    I am asked:

    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}}
