Homework Statement
y(5) - 2y(4) + y(3) = 0
This is 5th-order, linear, HG, with constant coefficients, and hence I used the characteristic equation:
m5 - 2m4 + m3 =
m3(m - 1)(m - 1) = 0
Hence, m = {1,1,0,0,0} and so the solution is given by:
y(x) = C1 + C2*x +C3*x2 + C4*exp(x) + c5*x*exp(x).
This is the Wolfram solution.
They seem to have an extra exponential term inside of the parentheses. Am I missing something?
Thanks!
