##### past midterm Q 3
« on: October 27, 2014, 10:07:03 PM »
the question 3 of past midterm says the following for using undetermined coefficient method on Euler equation:
Bonus
No: For Euler ODE the method of undetermined coecients requires the
right hand side to be P(ln t)tm , while it applies with P(t)emt (where in both
cases P(x) is a polynomial in x) only when the coecients of the ODE are
constants.
Can somebody help me to understand the solution to it.
