(1 point) In your answers below, for the variable i type the word lambda, for y type the word gamma; otherwise treat these as you would any other variable. We will solve the heat equation u, = 4uxx: 0<x<2, 120 with boundary/initial conditions: u(0,1) = 0, and u(x,0) = So, 0<x< 1 u(2, 1) = 0, 13, 1<x<2. This models temperature in a thin rod of length L = 2 with thermal diffusivity a = 4 where the temperature at...

(2 points) is typed as lambda, a as alpha. The PDE a2u ar2 = yº ди ay is separable, so we look for solutions of the form u(x, t) = X(x)Y(y). When solving DE in X and Y use the constants a and b for X and c for Y. The PDE can be rewritten using this solution as (placing constants in the DE for Y) into X"/X (1/(k^2))(y^5)(Y'/Y) = -2 Note: Use the prime notation for derivatives, so the...
