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

The very first 2 posts on MaplePrimes (first, second) show up on the last page with entries on recent posts. Today (Dec. 6, 2006), that happens to be page 63, although the last icon zaps one further to an empty page (another bug?). Anyways, it is interesting to see that those 2 posts were done 36 years and 49 weeks ago. Gotta love how MaplePrimes seriously pre-dates Maple itself!

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)

Playing with numerics for the hypergeometric function 2F1 i stumbled into the following exactness stuff, where lots of digits are lost and one needs to increase working precision quite a lot to get a good answer: f1 and f2 result from evaluating ugly, but usual transcendent functions, f3 comes through high precision and f0 is the limiting case.

  restart;
  
  hypergeom([1,2+epsilon],[3],z): 
  '%' = simplify(convert(%,StandardFunctions));
  theSol1:=rhs(%): 
  
  theSol1 = -2*(z*(1-z)^epsilon*epsilon-1+(1-z)^epsilon)/
    z^2/((1-z)^epsilon)/epsilon/(1+epsilon);
  is(%);

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

Is there a privacy statement somewhere on this site that one can read ? I was just wondering about the rights of users of Mapleprimes with respect to ownership of intellectual property after it is publicly released. For example, can Maplesoft and/or Mapleprimes use anything from the Mapleprimes site without the permission of the original author ? Was just wondering, v/r,

Sometimes when I reply to a forum posting, or look at some forum topics, the text box that would contain the body of the posting is misaligned from above formatting options, e.g. "I, B, spellcheck etc". It's pushed more to the right side of the screen, even after I scroll completely to the right. Thanks, Dan

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

Maple, Mathematica, and many other CAS define indefinite integral up to piecewise constants. That means, in particular, that the integral of a continuous function can be discontinuous. In many cases that can be easily fixed, such as for integrals involving floor(x) and frac(x). However, it has not been done neither in Maple nor in Mathematica. Here is another example, suggested by David W. Cantrell

int(1/(2+cos(x)),x);

               2/3*3^(1/2)*arctan(1/3*tan(1/2*x)*3^(1/2))

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.

Since Tom is travelling the world, I figured this would be an appropriate topic. Please vote in the new poll, how many countries have you visited?

I am currently in Kuala Lumpur teaching a Maple course and I'm showing the participants MaplePrimes ... say hi to our Malaysian friends. Salam! T4 from Universiti Kebangsaan Malaysia!

This page contains a great collection of different Maplets. Many users will be intersted in the Sudoku maplet. There are also some other interesting tools and games there. http://maplenet.msc.uky.edu/maplets/
