Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates. Find the maximum height above the \(x\)-axis of the cardioid \(r=1+\cos \theta\text{.}\) Sketch the graph of the curve whose ...

The graphs of \(y = \sin{\theta}\) and \(y = \cos{\theta}\) can be plotted. The graph of \(y = \sin{\theta}\) has a maximum value of 1 and a minimum value of -1. The graph has a period of 360°.

Identify and sketch the graph of the conic section defined by \begin{equation*} r=\frac{1}{2-4\cos \theta } \end{equation*} in the \(x\text{,}\) \(y\text{,}\) plane without converting it to cartesian ...
