Find all points (if any) of horizontal and vertical tangency to the portion of the curve shown. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
x = cos(?) + ? sin(?)
y = sin(?) − ? cos(?) −2? ≤ ? ≤ 2?
![**Problem Statement:**
Find all points (if any) of horizontal and vertical tangency to the portion of the curve shown. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.)
**Parametric Equations:**
\[ x = \cos(\theta) + \theta \sin(\theta) \]
\[ y = \sin(\theta) - \theta \cos(\theta) \]
\[ -2\pi \leq \theta \leq 2\pi \]
**Graph Description:**
The graph is a plot of the parametric equations described above, displaying a loopy curve within the Cartesian plane. It extends horizontally between approximately -8 and 6 on the x-axis and vertically between -8 and 8 on the y-axis. The curve has various loops, indicating complex behavior over the range of \(\theta\). The axes are labeled, with x and y marked at intervals of 2. The curve appears symmetrical along some parts and may have multiple points of tangency which need to be calculated.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffb4862a3-aaff-4cae-ab44-cc437a081d47%2Fa5ab4e87-f714-480d-8c07-a8e28c8f27b5%2F392who8_processed.png&w=3840&q=75)
