There is a patch attached to #6344 to change printing to alpha'(r) in latex mode. The syntax alpha'(r) would not be accepted on the command line without modifying the preparser, so normal printing is still a variant of the D notation. We can switch to using the diff notation when the function takes only one argument which is a symbol. As Maple does here: maple: diff(f(x),x); diff(f(x),x) maple: diff(f(x,x),x); D[1](f)(x,x)+D[2](f)(x,x) maple: diff(f(x^2),x); 2*D(f)(x^2)*x > And is it possible to get sin^2(x) ans (alpha'(r))^2 in LaTeX output > instead of sin(x)^2 and y'(r)^2? I don't think sin^2(x) is possible, (y'(r))^2 can be done. If we switch to that notation, I can make the necessary changes in pynac. Thanks.
