I was having hard time getting Mathematica to display x^-1 as x^-1 and not as 1/x. So I tried Maple 14, and it also does the same. So I thought I ask the maple experts here if there is a way to do this in Maple. This was my orginal question, I am posting it here for the Maple group. When I type x^-1 Maple replies 1/x Is there a way to tell Maple to *display* terms with negative powers as x^-n and not as 1/x^n ? (i.e keep the term just like it would appear on paper). Another example, suppose I type expr = a*x^-2 + b *x^-1 + The reason I want to do this, is just for display purposes. When I print the expression on the screen, I'd like it to look like x^-1 and not like 1/x (to better match how the expression look like in the textbook) thanks --Nasser

It also always uses the same order: cal, m, kg, s, A or V or ohm, K, mol. Neater methods may well exist!

Nasser, >Is there a way to tell Mathematica to >*display* terms with negative >powers as x^-n and not as 1/x^n ? There are many things that you will have to consider, but here goes a start: MakeBoxes[Power[x_, y_?(NumberQ[#] && Negative[#] &)], TraditionalForm] := SuperscriptBox[MakeBoxes[x, TraditionalForm], MakeBoxes[y, TraditionalForm]] MakeBoxes[Times[c_, p : Power[x_, y_?(NumberQ[#] && Negative[#] &)]], TraditionalForm] := If[OrderedQ[{c, p}], RowBox[{MakeBoxes[c, TraditionalForm], MakeBoxes[p, TraditionalForm]}...

I feel like a small child asking this, but how can I get Mathematica to say (x - 1) instead of (-1 + x), or to give me 4 (1 - q) instead of the doubly annoying -4 (-1 + q) ? In brief, given the choice, I prefer to look at subtraction rather than negation. The binary operator instead of the unary. I'm not asking Mathematica to read my mind about the way I want every possible expression to look, rather I am hoping to find out how to transform something I don't like into something I like, in a way that is guaranteed not to change the value of the expression.

Hi, I have a machine on a 192.168.x.x network that I would like to configure in such a way that it believes to be in 10.168.x.x. In other words, if a packet comes in from, say, 192.168.3.4, I would like it to be mangled as it was coming from 10.168.3.4. In the same way, I would like outgoing packets for 10.168.x.x to be mapped to 192.168.x.x. I read the iptables manual and found out abount DNAT and SNAT, but it seems what they do at most is mangle addresses into a pool of addresses, is a round robin fashion. I don't need round robin. I need a 1-1 mapping. Anybody knows if this is doab...

Hi everybody, Can somebody please help me out with the following problem: I want to use GAOT to maximizes f(x) under the constraint 0<=1-(x(1)+x(2)+x(3))<=1 This means I have to change the code of the GAOT toolbox at several places in order to decrease the search space of the ga (probably in the matutation file and the crossover file). Does somebody knows where??? Please help me out.. thanks alot in advance, I really appreciate your help!! take care Rick Duursma ...

--Apple-Mail-1--767860423 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed I'm against _premature_ optimization in theory, but believe that a certain innate knowledge of what is and what is not efficient is important for making reasonable choices in the first place. To that end, when I had to write code to handle exactly one case out of many, where I knew that the operator would be #==, I thought I'd test case versus if/elsif. As I expected, the case statement performed worse (thought not as much as I expected). On a w...

What exactly is the difference between the JRE 5.x and 6.x (or 1.5.x and 1.6.x) versions of the Sun Java Runtime Engine for windows? Why does Sun maintain 2 different versions or streams or forks of the JRE? Is it true that version 5 was supposed to have an EOL this past October - or was it always EOL in October 2009? How would my "internet browsing experience" be different if my system had the latest update of version 5 versus version 6? Is it true that version 6 is somehow optimized or faster than 5? sm5w2@yahoo.com wrote: > What exactly is the difference between the JRE 5....

This is a thought experiment. First, in RM 4.1.6: * when the generalized_indexing is used within a primary where a name denoting a constant is permitted. This means declare package V is new Vectors (Complex); X : V.Vector; begin X (1).Re := X (1).Re + 1; end; is interpreted as declare package V is new Vectors (Complex); X : V.Vector; begin Reference (X, 1).Element.all.Re := Constant_Reference (X, 1).Element.all.Re + 1; end; Is this OK? If this is the truth, and if Vectors is implemented by reference-counting. (I don't know copy-on-write is permitted in Ada.Contain...

Dear All, I've just released the newest version of Mac Graphviz, featuring shapefile support and enhanced zoom. http://www.pixelglow.com/graphviz/ Shapefiles supported include PDF, EPS, PS, JPEG, PNG and all Quicktime formats. Either specify an absolute or relative (to working directory) file path, or a URL using the shapefile attribute. Developers can now also use the graphviz.framework directly with #include headers in C e.g. using Xcode "Add Frameworks..."; documentation is available from the main Graphviz site -- http://www.research.att.com/sw/tools/graphviz/libguide.pdf...
