Title: past midterm Q 3
Post by: Tony Shan 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 coecients 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 coecients of the ODE are
constants.
Can somebody help me to understand the solution to it.

THe bonus question asks if the particular method is applicable to some particular equation

The answer was: No
And rationale was provided
