How to use maple "odetest" to check a solution.

This check applies to all midterm 3 problems. Problem 4 is
checked by this same test, because it tests the DE instead of
the solution.

EXAMPLE:

  sol:=y(x)=(x^2/4-x/4)*exp(x);
  de:=diff(y(x),x,x)-y(x)=x*exp(x);
  odetest(sol,de);

  The test returns zero (0) if it works. If any nonzero
  expression prints, then it failed.

MORE INFORMATION:

  ?odetest
