Let x- rcose and y -rsin6 to transform f(x,y,z) to g(r,6,z) Hint: Use the Laplacian for polar coordinates to replace fx+ fyy Let f:R3- R be a function with continuous second partial derivatives. 22] The Laplacian in Cylindrical and Spherical Coordinates.

Solve a 3-D parabolic PDE problem by reducing the problem to 2-D using coordinate transformation.

This example uses the PDE Modeler app. In this section we will define the spherical coordinate system, yet another alternate coordinate system for the three dimensional coordinate system.

The first few functions are shown in the figure. (6-54), namely, X = r sin 0 cos cp, (1) y = r sin 0 sin (p (2) and z = r cos 0. They have infinitely many zeroes.

After rectangular (aka Cartesian) coordinates, the two most common an useful coordinate systems in 3 dimensions are cylindrical coordinates (sometimes called cylindrical polar coordinates) and spherical coordinates (sometimes called spherical polar coordinates).

Note that the cylindrical system is an appropriate choice for the preceding example because the problem can be expressed with the minimum number of varying coordinates in the cylindrical system. 6-5 and by Eq. The Laplacian is (13) Let (14) (15) (16) Then the new Scale Factors are (17) (18) (19) The Helmholtz Differential Equation is Separable. Laplace's Equation in Cylindrical Coordinates: Use the relationships between the Cartesian (x, y, z) and cylindrical (s,φ, z) coordinates and the chain rule to show that the Laplacian operator in the Cartesian basis: is equivalent to the Laplacian operator in the cylindrical basis: For example,

a. Cylindrical Coordinates. All of them, except for J0, are zero at x =0. They were defined in Fig. In this lecture separation in cylindrical coordinates is ... the end caps and the cylindrical wall is at zero potential, Figure 4. The Bessel functions (Js) are well behaved both at the origin and as x →∞. Appendix V: The Laplacian Operator in Spherical Coordinates Spherical coordinates were introduced in Section 6.4. A thoughtful choice of coordinate system can make a problem much easier to solve, whereas a poor choice can lead to unnecessarily complex calculations.

Cylindrical and spherical coordinates give us the flexibility to select a coordinate system appropriate to the problem at hand.
