Answer
negative
Work Step by Step
RECALL:
The quadrantal angles are (for clockwise movement from the positive x-axis):
Positive x-axis: $0$ radians;
Negative y-axis: $-\frac{3.14}{2} = -1.57$ radians;
Negative x-axis: $-3.14$ radians;
Positive y-axis: $-4.61$ radians
Positive x-axis: $-6.28$ radians
Thus, when moving clockwise from the positive x-axis, the angle $-6,29$ radians is right after the positive x-axis after one rotation.
This means that the angle is in Quadrant IV.
With $\tan{\theta}=\frac{y}{x}$, and since $x$ is positive and $y$ is negative in Quadrant IV, then $\tan{(-6.29)}$ must be negative.
