    |dw:1328634940137:dw|\[\csc(x)=\frac{2}{1} (=\frac{hyp}{opp})\] Draw a right triangle and label the sides base on this equation. Keep in mind cos(x)<0 So we want (-,+)

    so we have the adj side is -sqrt(3)

    \[\tan(x)= \frac{1}{-\sqrt{3}} (=\frac{opp}{adj})\]

    one more example \[\sec(x)=\frac{2}{-\sqrt{3}} (=\frac{hyp}{adj})\]
