Hi Tapan,
Welcome to Maxima.
I don't use TeXmac, but probably someone else will help you with that.
I will try to give you a couple of ideas regarding your question 3).
1) Using the idea you are familiar with from Maple:
f(r) := subst(r,t,diff(v(t),t));
2) define(f(r), diff(v(r),r));
3) f(r) := ''(diff(v(r),r));
You can try to find Maxima manual (a pdf file) somewhere in your
Maxima instalation, or visit Maxima Web site: http://maxima.sf.net,
and explore the "Docs" link.
While in a Maxima session, typing "? command " should give you
some description of that command, or (often) a list of related maxima
commands. Try, for example, "? define "
Hope this helps.
