In mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a function on Euclidean space.It is usually denoted by the symbols ∇·∇, ∇ 2 (where ∇ is the nabla operator) or Δ.In a Cartesian coordinate system, the Laplacian is given by the sum of second partial derivatives of the function with respect to each independent variable Your underbrace ?? is the angular part of kinetic energy operator. Your underbrace $\nabla^2$ is the radial part of the kinetic energy operator. That is convenient, because spherical harmonics are the eigenfunctions of L^2, and whole expression can be made angle independent. $\endgroup$ - Mikael Kuisma Jan 18 '16 at 9:0

How to Solve Laplace's Equation in Spherical Coordinates

coordinate system will be introduced and explained. We will be mainly interested to nd out gen-eral expressions for the gradient, the divergence and the curl of scalar and vector elds. Speci c applications to the widely used cylindrical and spherical systems will conclude this lecture. 1 The concept of orthogonal curvilinear coordinates Spherical coordinates are better because they reflect the spherical symmetry of a rotating molecule. Spherical coordinates have the advantage that motion in a circle can be described by using only a single coordinate. For example, as shown in Figure \(\PageIndex{2}\), changing φ describes rotation around the z‑axis This approach is useful when f is given in rectangular coordinates but you want to write the gradient in your coordinate system, or if you are unsure of the relation between ds 2 and distance in that coordinate system. Exercises: 9.7 Do this computation out explicitly in polar coordinates. 9.8 Do it as well in spherical coordinates Here, in the Navier's equation u is the displacement vector, ∇ (∂/∂r in the Cartesian coordinate system) represents the nabla operator, F is a body force, d and c are the material parameters; density and elastic constant (generally tensor), respectively. In the Maxwell's equations, D is the electric displacement vector, E is the electric field vector, B is the magnetic flux density.

Secret knowledge: elliptical coordinates; Laplace operator in polar coordinates. 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 The del operator in polar coordinates. In Cartesian coordinates, the del operator takes the same form when applied to scalar and vector functions. This is not the case in polar (spherical or cylindrical) coordinates

Now we gather all the terms to write the Laplacian operator in spherical coordinates: This can be rewritten in a slightly tidier form: Notice that multiplying the whole operator by r 2 completely separates the angular terms from the radial term. That is why all that work was worthwhile Deriving Divergence in Cylindrical and Spherical. Let's talk about getting the divergence formula in cylindrical first. Later by analogy you can work for the spherical coordinate system. As read from above we can easily derive the divergence formula in Cartesian which is as below In the spherical coordinate system, we again use an ordered triple to describe the location of a point in space. In this case, the triple describes one distance and two angles. Spherical coordinates make it simple to describe a sphere, just as cylindrical coordinates make it easy to describe a cylinder Thus, I want to use the $\nabla$-operator in spherical coordinates. Therefore I also need the Pauli vector in these coordinates. homework-and-exercises coordinate-systems. share | cite | improve this question | follow | edited May 19 at 19:51
