Evaluate tan(-330)?

Question

is it Is it $\frac{\frac{1}{2}}{\frac{\sqrt{3}}{3}} = \frac{\sqrt{3}}{3}$ $(1/2)/(sqrt3/3)=sqrt3/3$ ? Since this is a negative angle, I'm not sure of where to put the positive and negative signs

$\frac{\sqrt{3}}{3}$ $sqrt3/3$

tan (-330) = tan (30 - 360) = tan 30
Trig table gives --> $tan 30 = \frac{\sqrt{3}}{3}$ $tan 30 = sqrt3/3$
