This is my question.

Use the equilibrium solution to transform the following IBVP for the heat equation to a homogeneous one. Then use the method of separation of variables with -A as the separation constant to find the solution u(x, t). Show all steps, including a proof of the sign of 1. Simplify your answer as much as possible. Ut = Unx - et, 00 u(0, t) = ux( 7, t) = 0, u(x, 0) = f(I), 0 (...), use SUM( . . ., i=1. . infinity) . For typing an integral like ( f(x) d.x, use int (f (x) , x=a. .b)
