Provide an appropriate response.
-Find any horizontal or vertical asymptotes for the curve $r = 4 \tan \theta , 0 \leq \theta \leq 2 \pi$ . (Suggestion: Express the curve in parametric form $( \mathrm { x } = \mathrm { r } \cos \theta , \mathrm { y } = \mathrm { r } \sin \theta )$ and investigate what happens to $\mathrm { x }$ and $\mathrm { y }$ as $\theta$ varies.)
