comment How do I tweak the input assistant to use string completion on my own functions?
See, the linked is exactly the question I was looking for before I posted but I thought "string completion" was the right search term - I will see what I can do with it and if it is as easy as your answer there makes it look, I will delete this as duplicate. Thanks!

comment Transformation of Derivatives under change of coordinates
You can look at the FullForm of your expression and apply a simple replacement rule like Derivative[0, 1][a_][t, z] :> (Derivative[0, 1][a][xm, xp] + Derivative[1, 0][a][xm, xp]) for each of your light cone coordinates

Is your purpose to do this real-time? I doubt you will be able to manipulate a sound in real time with mathematica.

Now I sat down and played with it, you are right: this makes absolutely no sense at all to me!

comment How can I get the function of a plotted trajectory?
Amir, there are a few things problematic with this. Primarily I have a strong feeling you are using -g in place of g. Since your equations are decoupled in y and q you can solve each analytically and then try and fulfil the i.c.'s which will spit out an inconsistency in y. You can edit in the code you are using to your question (make sure you read the guide on how to format your question )

comment Example of Integrate applying a numerical evaluation N
I was always under the impression that that's what machine precision did to Integrate. Check out Integrate[Cos[x], {x, 1, 2}] vs Integrate[Cos[x], {x, 1., 2}] for instance.

Thanks - It's cause the limits have been expressed in machine precision arithmetic

comment How to define a nestable Baseform function, BaseForm output becomes BaseForm input
thanks - so then it is just an issue of defining a function that works on BaseForm. What I didn't understand why you'd want to go through the process of jumping from base to base but if it is on potentially stored numbers it makes sense.
