Use even and odd properties of the trigonometric functions to find the exact value of the expression. csc (-pi/6)
you know csc is 1/sin, right? and sin is odd function
so csc is also odd, then it will be obvious to find the answer
would it be 2 or -2?
-2, since f(-x)=-f(x), you may take out the - sign first and then calculate
its -2 ... unit circle will really help you with this http://en.wikipedia.org/wiki/File:Unit_circle_angles_color.svg
