Question

The statement "tan $\theta = -\frac{12}{5}$, csc $\theta = -\frac{13}{12}$, and the terminal point determined by $\theta$ is in quadrant 3":

cannot be true because tan is greater than zero in quadrant 3.

cannot be true because tan must be less than 1.

cannot be true because $12^2 + 5^2 \neq 1$.

cannot be true because if $\tan \theta = -\frac{12}{5}$, then csc $\theta = \pm \frac{13}{5}$.

Answer: cannot be true because tan is greater than zero in quadrant 3.

Question

Check all that apply. $\tan \theta$ is undefined for $\theta = \_$.

π

$\frac{\pi}{2}$
