Unformatted text preview: assume that when you set the equations equal to a separation constant − λ , the cases λ = 0 and
λ = −α 2 give trivial solutions.
This is known as the HeatNeumann model. Assume , = = , ,0 = , = 0, and plug this into PDE to get = Case 1: λ = 0 → = 0 Trivial solution
Case 2: λ = −α 2 → = 0 Trivial solution
Case 3: : λ = α 2 =−λ =0 4 5
5.) [10 points] A string of length π has tension constant a and has its two ends clamped at the
xaxis. Assuming the string is released from rest, the vertical displacement u(x,t) of the string is
modeled by = 0, , Suppose the string has initial shape = , = 0, ,0 = 0 , 0 = sin for some integer...
