Evaluate the trigonometric function of the given quadrantal angle. If the value is undefined, write "undefined."
-$\tan 720 ^ { \circ }$
A) undefined
B) 0
C) $- 1$
D) 1

Question

Quizplus · Accepted Answer

The tangent of 720 degrees is 0 because 720 degrees is equivalent to 2 full rotations (360 degrees each), bringing us back to the starting point on the unit circle where the angle is 0 degrees, and $\tan(0) = 0$.
