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.

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.

Hi all, I am new with maple! I want know if maple has the some tools to create a GUI as matlab. Is there a function "patch" as matlab? Regards

define(h,'orderless',h(1,2)=3); works as I would expect and h(1,2) and h(2,1) evaluate to 3. define(h,'orderless',h(2,1)=3); gives both h(1,2) and h(2,1) evaluating just to h(1,2). I suspect this is a bug since replacing 1,2 by a,b or by b,a it works as I would expect. Is this (another) fundamental bug or have I misunderstood something? I'd be interested in any comments.

Sequence A125033 in the OEIS submitted by Paul D. Hanna and Richard J. Mathar, is defined as Number of labeled nodes in generation n of a rooted tree where a node with label k has k child nodes with distinct labels, such that each child node is assigned the least unused label in the path that leads back to the root node with label '1'.

I have installed Maple10 on Windows XP, but when I execute "maplew.exe", Maple doesnt start. I can only start the classic Worksheet. Can you help me please?

The other day I was doing some not so light recreational reading. On page 83 of GAMMA Julian Havil
discusses the Bernoulli numbers. Evidently there exists a set of numbers B(0), B(1), ... such that

sum(k^pwr,k=1..n) = (1/(pwr+1)) * sum((n^i) * B(pwr+1-i)* binomial(pwr+1,pwr+1 - i),i=1..pwr+1)

Havil listed the first 12 Bernoulli numbers B0, B1, ..... = 1 1/2 1/6 0 -1/30 0 1/42 0 -1/30 0 5/66 0, ...

He also stated that the Bernoulli numbers were part of the coefficients of the expansion of x / [ (exp(x) -1)]
