Eq.(Q4-1) Consider the following heat equation Uxx(x, t) - u(x, t) = 0, (0<x<10, 0<t<..) with the given boundary conditions u(0,t) = 0, u(10,t) = 0, (0<t<) and initial condition u(x,0) = f(x), (0 < x < 10) Eq.(Q4-2) Eq.(Q4-3) (a). (5 points) After calculations, u(x, t) can be expressed by the following series n 10 2 t ηπα e 10 u(x, t) = &n=1 Kn sin where Ki's are some constants satisfying Eq.(Q4-1) and boundary conditions. Find an expression for K, such that u(x,t) also satisfies the initial condition. (x, (b). (10 points) For 0<x<5, f(x) = {i (10 - x, 5 sx < 10 Find K. Eq.(Q4-4) (c). (10 points) Now, if the original boundary conditions Eq.(Q4-2) are replaced by the following new ones: u 0,t) = uz (10,t) = 0, (0 <t<.) Eq.(Q4-5) Find the solution u(x, t) satisfying boundary conditions Eq.(Q4-5) and initial condition Eq.(Q4-3).
