The two dimensional wave equation - Trinity University
ramanujan.math.trinity.eduThe 2D wave equation Separation of variables Superposition Examples The first equality becomes T′′ −c2AT = 0. The second can be rewritten as X′′ X = − Y′′ Y +A. Once again, the two sides involve unrelated variables, so both are constant: X′′ X = B = − Y′′ Y +A. If we let C = A−B these equations can be rewritten as X ...
LAPLACE’S EQUATION IN SPHERICAL COORDINATES
www.dslavsk.sites.luc.eduThis is the form of Laplace’s equation we have to solve if we want to find the electric potential in spherical coordinates. First, let’s apply the method of separable variables to this equation to obtain a general solution of Laplace’s equation, and then we will use our general solution to solve a few different problems.

Lecture 10 Optimization problems for multivariable functions
links.uwaterloo.caUp to now, we have encountered three types of critical points for functions f(x,y) of two variables: 1. Local minima: The point (0,0) is a local minimum for the function f(x,y) = x2 + y2, the graph of which is sketched below. O x y z z = x2 +y2 A plot of the countours/level sets of this function will also help us to understand the behaviour
