I also tried Defer[D[r,{t,2}]] but instead of D[..] I used the Palette symbol for differentiating something twice....the output it gave for the denominator was dt dt instead of d^2 t.....how come???....if I insert 3, I get dt dt dt...etc... thanks...jerry blimbaum.... -----Original Message----- From: Dave Snead Sent: Wednesday, May 09, 2012 2:50 AM To: mathgroup at smc.vnet.net Subject: [mg126433] Re: Typesetting built-in functions without evaluating Brentt-- Defer[D[x,y]] will display the partial derivative in traditional form --Dave Snead -----Original Message----- From: Brentt Sent: Tuesday, May 08, 2012 1:08 AM To: mathgroup at smc.vnet.net Subject: [mg126433] Typesetting built-in functions without evaluating Hello, I've been wrestling with mathematica trying to get it to typeset a partial derivative in traditiaonal form without evaluating it. The closest I've been able to come is having it output in[1]:=D[x,y] //TraditionalForm out[2]:=Hold[ *typesetted partial derivative here* ] So I can get the unevaluated partial derivative notation to output, but I can't do it without having the "Hold" mucking it up. How might one go about this? I've tried all kinds of complicated schemes, and I'm sure I could hack together some sort of output form that looks like a pd but that is actually not. But I figure there has to be a simpler solution that I'm missing. Also I've tried setting D to HoldAll. It doesn't work for some reason and I'm not sure why? Evaluation order is still a dark art to me despite having read that portion of the manual a few times (in my defense I'm not the sharpest tool in the shed).
