The second angle is used in polar coordinates in the standard ellipse and is measured from center of the circles. We call it $\theta_{polar}$ as usual. Green radial line. For an ellipse axes $(a,b)$ along $(x,y)$ coordinate axes respectively centered at origin given Wiki expression is obtained in polar coordinates thus: Plug in
I was having some problem when trying to come out a polar coordinate function with straight line equation. I know it is not good to post images here, but please bear with me as the question requi...
The gradient operator in 2-dimensional Cartesian coordinates is $$ \nabla=\hat{\pmb e}_{x}\frac{\partial}{\partial x}+\hat{\pmb e}_{y}\frac{\partial}{\partial y ...
Hint Suppose we want to define new coordinates $(R, \Theta)$ using a reference point $(\rho, \alpha)$ given in the original polar coordinates $(r, \theta)$. Then, the old polar coordinates $(r, \theta)$ and new polar coordinates $(R, \Theta)$ of the arbitrary (red) point are related as in the diagram below.
Show that in polar coordinates, the Cauchy-Riemann equations take the form $\dfrac{\partial u}{\partial r} = \dfrac{1}r \dfrac{\partial v}{\partial \theta}$ and ...
$\begingroup$ Right now, your answer looks like a "link only" (or citation only) answer. As the goal of MSE is to provide a more-or-less self-contained repository of questions and answers, it would be preferable if you expended some words to explain what is contained in those references and how it applies to the question being asked.

Take a simple polar equation like r = θ/2 that graphs out to: But, how would I achieve a rotation of the light-grey plot in this image (roughly 135 degrees)? Is there a way to easily shift the plot?
