Answer
Explanation:
Step1: Recall polar - curve forms
The general form of a limacon in polar coordinates is $r = a\pm b\cos\theta$ or $r=a\pm b\sin\theta$.
Step2: Identify the curve type
Given $r = 2+\cos\theta$, where $a = 2$ and $b = 1$. Since it is in the form $r=a + b\cos\theta$, it represents a limacon.
Answer:
limacon
