13 Question 12: ( Email Solution Code+Plots): Find the solution for 2D Laplace's equation in polar coordinates for the equilibrium temperature ur. @). The solution should be in Matlab using a finite aifference method. The radius of the disk is r = 1 as well as the cartesian domain in x-direction is (-1. 1] and [-1. 1] in y direction. The temperature at the boundary of the disk is fixed at u(e) = sin(e). (15 Points) TO Laplace's equation in polar coordinates is given by: 17 au ni o 13 Question 12: ( Email Solution Code+Plots): Find the solution for 2D Laplace's equation in polar coordinates for the equilibrium temperature ur. @).
