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 ...

Express the polar equation \(r=\cos 2\theta\) in rectangular coordinates.

Abstract: Power system analysis algorithms under polar coordinates are traditionally implemented with the polar form complex number, which is abstracted as phase and magnitude. This paper addresses a ...
