Keywords: Laplace’s equation, curvilinear coordinates, capacitance, harmonic functions, separation of variables. The paper is distributed as follows: In section 1, we solve Laplace’s equation in generalized geometrical congurations to obtain the BHF’s, by using a generic system of curvilinear
B.2 Polar coordinates. Let us consider the vector Poisson equation ‘:u = f in two dimensions expressed. in polar coordinates (r, ?). The Laplace operator in this coordinate system is. the vector field u being expressed in its polar components (un uq,) according to.

In polar coordinates there is literally an infinite number of coordinates for a given point. For instance, the following four points are all coordinates for the same point. The equation of a circle centered at the origin has a very nice equation, unlike the corresponding equation in Cartesian coordinates.
In cylindrical coordinates, Laplace’s equation is written. (396). Note that we have selected exponential, rather than oscillating, solutions in the -direction [by writing , instead of , in Equation (399)].

Polar coordinates use an origin, O, and a horizontal line serving as the reference line from which to measure angles of rotation, , in an anti-clockwise manner. The connection between Cartesian coordinates and Polar coordinates is established by basic trigonometry.
In mathematics, log-polar coordinates (or logarithmic polar coordinates) is a coordinate system in two dimensions, where a point is identified by two numbers, one for the logarithm of the distance to a certain point, and one for an angle.
Laplace’s equation in the Polar Coordinate System As I mentioned in my lecture, if you want to solve a partial differential equa-tion (PDE) on the domain whose shape is a 2D disk, it is much more convenient. Product.solutions.of.Laplace.equation.in.Polar.coordinates.1. Uploaded by. Sonam Rohatgi. This suggests (and easy to verify) that. (Ar v ? + Br ? v ? )(C cos( v ??) + D sin( v ??). is a product solution of Laplace’s equation whenever A, B, C, D ? R and ? > 0.
To find area in polar coordinates of curve on interval [a,b] we use same idea as in calculating area in rectangular coordinates. So, consider region Example 2. Consider limacon r=3+2cos(theta) and circle r=2. Find area inside limacon and outside circle, outside limacon and inside circle, inside both

Laplace operator in spherical coordinates. Special knowledge: Generalization. In the next several lectures we are going to consider Laplace equation in the disk and similar domains and separate variables there but for this purpose we need to express Laplace operator in polar coordinates.
