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 ...

Polar coordinates are an alternative coordinate system to the commonly used Cartesian (rectangular) coordinates. They are particularly useful in situations where data can be more easily represented ...

Abstract: This paper proposes a means by which 2D data represented using the rectangular coordinate system can be converted to its equivalent in the polar coordinate system. Taking note that the order ...

Abstract: Prior knowledge utilizing Channel State Information (CSI) and the precise spatial coordinates is imperative for accurately determining an individual’s whereabouts through the utilization of ...

Traditional single-pixel imaging uses Fourier patterns to modulate objects in the Cartesian coordinate system. The Cartesian Fourier pattern of single-pixel imaging is inappropriate to display in a ...
