Okay I understand the majority of this problem, but there's just one part that I don't understand! Problem: Given that x is in Quadrant II, and cscx=3, find the values of all six trigonometric functions of x. So when i draw the triangle in Quadrant II, I got y=1, r=3, and on the key x=square root of 8. I understand how y and r were found, but how was x found?

Pythagoras's theorem requires x^2 + y^2 = r^2, but x is negative for points in the second (or third) quadrant.
