How does one assign from a solution set? In the following example, I would like to get the square roots of b and c where when solved, b=9 and c=10. How does one assigned the values obtained in the solution to be able to manipulate them later? Thanks. > `πx`^2 = `kπ`(y^2-x^2); print(`πx`^2 = `kπ`(y^2-x^2)); 2 / 2 2\ πx = kπ\y - x / > `kπ`(y^2-x^2) = Pi(z^2-y^2); print(`kπ`(y^2-x^2) = Pi(z^2-y^2)); / 2 2\ / 2 2\ kπ\y - x / = Pi\z - y / > `πx`^2 = `kπ`(z^2-y^2);

I am attempting to do some game theory models for the collectible card game Legend of the Five Rings (www.l5r.com). The problem I am having is Polymorphisms, Inheritance, and Constructors in Maple 10. The game consists of several Card Types, each with distinct characteristics. I want to define a construtor module called CARD. It will have a TITLE and along with procedures getTitle() and setTitle(String). I then want to have a constructor module called HOLDING that is a CARD and has all the characteristic and procedures of CARD, but also a variable GOLDPRODUTION and procedures getGoldProduction and setGoldProduction.

I am trying to create my own package (module). I have read a lot helps in Maple and search this forum. But I don't know why this doesnt work 1. There is no file in /home/rno/math/maple/lib/ rno@amd:~/tmp> ls -l /home/rno/math/maple/lib/ razem 0 (it is in polish; it means there is no file) 2. The Maple script look like this: rno@amd:~/tmp> cat convacc.mp MyModule := module() export f1, f2, f3; local loc1; option package; description "Ala ma kota"; f1 := proc() eval(loc1); end proc; f2 := proc( v ) loc1 := v; end proc;

I have just bought a new labtop computer... A fujitsu siemens. With 1.6 Dual core, 512 MB ram and Windows XP pro. At my university we are handed out the cd's for selfinstallation, but this time it doesn't seem to work. My errors are InvocationTargetException errors, even before installation begins. I have searched the internet empty for solutions, but none have seemed to help. The same problem was encountered by rhorrox, see: http://www.mapleprimes.com/forum/maple-10-failing-on-install I have therefore tried different medias, I have burned the iso-image, this is what were handed out, and tried installing from a cd. I have also tried mounting the iso via Daemon tools. Both with the same errors.

The appearance of this thread has degraded over the years, but most all post about the MRB constant can be found by entering "MRB constant" into the search box.

Hi, I am using Maple on Mac for about ten years. For some reason, Maple 10 starts unacceptably slowly on my 800 MHz G4 with 1GB RAM. It takes about 30 seconds to start and open a fresh worksheet. It takes about 50 seconds to start and open a saved worksheet of 100 kB. The only advice I could get from other users in my country (Czech Republic) was to put away all palettes. Although this made the start of Maple faster, the general picture remained the same. Basically, this is why I abandoned Maple 10 altogether. Because of poor readability and annoying bug in GUI of Maple 9.5 ("Execute selection" never stops at the end of a selection), I still mostly use Maple V.4, as do many of my colleagues. I think this should be alerting to Maplesoft.

We want to know what Waterloo has done about using full 64 bit performance in VISTA and multicore and parallel computing. Pros, please tell us; we want our supercomputer abilities now!

Is there a way to save your completed, final maple documents as a PDF ? Right now I'm printing them out and scanning them in order have a soft copy of my documents. v/r, Dan

I wonder if someone out there would help me understand the inner workings of MAPLE as indicated by the following: MAPLE has no trouble with int(sqrt(1-x^2)-x1,x=x1..sqrt(1-x1^2)); nor with this f1:=x->sqrt(1-x^2)-x1:int(f1(x),x=x1..sqrt(1-x1^2)); this one works too int(sqrt(r^2-x^2)-x1,x=x1..sqrt(r^2-x1^2)) assuming r>0,x1>0,r>x1; but for some reason not this one f2:=x->sqrt(r^2-x^2)-x1:int(f2(x),x=x1..sqrt(r^2-x1^2)) assuming r>0,x1>0,r>x1; Curiously, this works gg:=x->sqrt(r^2-x^2)-x1:int(gg(x),x):z:=unapply(%,x):z(sqrt(r^2-x1^2))-z(x1)

Here is my problem: #1 > plot([fx,x+6],x=-20..20,y=-15..20,color=red, thickness=2); Warning, unable to evaluate 1 of the 2 functions to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct graph a-e) > fx:=((x+2)^3)/((x^2)-1); equation

Is anyone here working on any of the millenium prize problems ? If so, or if you know of any efforts on one of these problems, do you know if Maple would be of any use ? v/r, dc

Does anyone know how one would go about creating their own package ? thanks, Dan

A couple of years ago I did the following work on Trigonometric integration. Does anyone have any improvements to add to it? I would like to see it expanded to all complex numbers. I'll soon be working on it again. Download 565_Pre_exp[1].doc

My Maple 10 software won't load on my computer. When i try to open it, the splash screen shows and stays for about a minute and then closes without opening maple at all. No error messages or anything, but maplew.exe shows in my windows task manager processes list. I'm running windows XP media center edition, core2duo 2.16, 2GB 667 ram, 100gig 7200. I'd appreciate any help i can get, thanks for your replies.
