**Linear Differential Operator in Maple: Current Progress**

Below is a summary of my understanding of creating the operator L in Maple. I've figured out how to apply this operator to an arbitrary function f(x), however i'm currently trying to figure out how to convert the D operator into diff(f(x),x) when applied to f(x). I believe I have to use the built in convert() function to accomplish this task. After the operators have been converted to diff() form it should be possible to plug the equations into Maples built in differential equation solving functions.
