Write down the solution to the boundary value problem ∂t
∂u
=4 ∂x 2
∂ 2
u
on the interval [0,4] with the boundary conditions u(0,t)=u(4,t)=0 for all t subject to the initial conditions u(x,0)=h(x). As before, please choose the correct option: does your answer only include odd values of k, even values of k, or all values of k ? u(x,t)=∑ k=1
[infinity]
Which values of k should be included in this summation? A. Only the even values B. Only the odd values C. All values
