please answer compleltly 2. Find the eigenfunctions and eigenvalues for the differential equation d^2u(x)/dr^2 = -k^2 u(x) in the interval 0 < = x < = a, assuming k is a real number, for the following sets of boundary conditions: (a) bu(0)+cdu/dt|x=0 =0 and bu(a)+cdu/dx|x=a =0 (b) u(0)+a du/dx|x=0 =0 and u(a)-adu/dx|x=a =0 You need not normalize the eigenfunctions. For (b), find the equation which determines the eigenvalues and verify that there is an infinite set of eigenfunctions and eigenvalues;...
Consider a uniform bar of length L having an initial temperature distribution given by f(x), 0 < x < L. Assume that the temperature at the end x=0 is held at 0°C, while the end x=L is thermally insulated. Heat is lost from the lateral surface of the bar into a surrounding medium. The temperature u(x, t) satisfies the following partial differential equation and boundary conditions aluxx – Bu = Ut, 0<x<l, t> 0 u(0,t) = 0, uz (L, t)...
