Hello! I upload my file which has a problem. I am not an expert on MAPLE v10.05. The file name is "mapleprime-2". I try to get a solution of four equations with the symmetric assumption for time variables. Anyone could change the assumption to get a result. Or, anyone could add just two more time variables: t[6] with minus sign amplitude and t[7] with plus sign amplitude. So, the entire number of time variables are still odd number which can not be changed. The current code is following as: restart: eq1:=expand(sum((-1)^(i+1)*cos(w*t[i]),i=1..5)=0): eq2:=expand(sum((-1)^(i+1)*sin(w*t[i]),i=1..5)=0):

Happy Holidays and Merry Christmas to all MaplePrimes members. I hope you all have a great time with whatever you are doing for the rest of 2006. In honor of the season, here is a nice holiday image, courtesy of the Calculus II Powertool.

So, is there any information about Maple 11, or do we have to wait until the Joint Meeting to find out? Just curious if anyone has found anything out or knows anything about the next version!

I'm currently a student at the University of Bolton. I'm on the Computer Games Software Development course, and as part of our first year we do some basic mathematics, followed by basic physics in the next semester. Now most of this - all right, all of it - is old hat to me, but it's still interesting, particularly when Maple gets involved, which I'd never used before starting the course. We recently had to complete a coursework assessment using Maple, and one of the requirements was to create a 'scene' using Maple - so it was lots of transformations, seq() and such. I don't know what the majority of the others did, but seeing as I'm on a games course... well, there was only one thing it could be! It's at the end of the sheet below.

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.

The audience for this video of a blind date between exp(1) and Pi is not huge, but to the right one it is quite funny!

Does anyone know how to work out the largest triangle that can be enclosed within an ellipse (both in 2D)? For any triangle, Area:=sqrt(s*(s-a)*(s-b)*(s-c)) where s:=(a+b+c)/2 and a,b,c are the length of the sides. Say the ellipse is equation 1/9*x^2+1/4*y^2 = 1 hence y: = -2/3*(-x^2+9)^(1/2) or +2/3*(-x^2+9)^(1/2) Given three points (x1,y1), (x2,y2), (x3,y3) Eg distance from (-x1,-y) to (-x2,y) with(student): a:=distance([-x1, subs(x=-x1,-2/3*(-x^2+9)^(1/2) )], [-x2, subs(x=-x2, +2/3*(-x^2+9)^(1/2))]); (note the sign of y) and so forth for b and c. there has to be a more eloquent (calculus) way.

So you think you really want to know what Maple does? Are you really sure? Well, here is how old-timers do it. [I do not claim that this is either the best or the modern way to do it, just that this is how people with over 10 years of Maple experience do it].

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;

hello? I wrote the following equations to be solved. restart; eq1:=expand(sum((-1)^(i+1)*cos(omega*t[i]),i=1..5)=0): eq2:=expand(sum((-1)^(i+1)*sin(omega*t[i]),i=1..5)=0): eq3:=expand(sum((-1)^(i+1)*cos(r*omega*t[i]),i=1..5)=0): eq4:=expand(sum((-1)^(i+1)*sin(r*omega*t[i]),i=1..5)=0): t[1]=0;t[4]:=2*t[3]-t[2];t[5]:=2*t[3]; _EnvAllSolutions:=true: _EnvExplicit:=true: s1:=solve({eq1,eq2,eq3,eq4},{t[2],t[3],r}); Do I have to specify t[3]>t[2], t[2]>0 in the code? where t[1] to t[5] are time variables starting from t[1]=0 and omega and r are constants. How can I get the solutions for t[2] and t[3]?

I want to use dsolve (Maple 10) to iteratively solve two systems of ODEs adjusting the boundary conditions until the solutions match at a fitting point. My problem is that the output of dsolve is a set of functions, and, each time dsolve is called, the solutions might not be reported in the same order as the last time dsolve was called. This makes it difficult to write a routine that compares the results of each iteration. I would appreciate any advice on how to extract the solutions from the dsolve output. Thanks. Glenn

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.
