Hi.. been using maple v.10 for a few days now.. I created a maple sheet for newton's method of approximation.

The aim was to find F(x) = 0, my final value for Xo was −1.509410457

I wanted to know, how to create a situation where Xo is continuously replaced with Xnew until Xo = Xnew.

Here's my code:

> restart;

> Xo:=-2;

> F(x):=(Xo^5) + 3*((Xo)^2)+1;

> dFx:=5*((Xo)^4) + 6*(Xo);

>

>

Xo := -2

F(x) := -19

dFx := 68

> Xnew:=Xo - ((F(x))/dFx);

.............-117
Xnew := ----

Hello, I am trying to solve this PDE using the Method of Lines and so I turn it into N ODEs. The following is how I plan on solving it; p1:=proc(N,x,Y,YP) FD:=proc(i,N,Y) if (i=1) then "use this stencil (like (Y[1] - Y[2]) / 60*dx); elif (i=2) then "another stencil"; ... ... else "last, general stencil"; end if; end proc; SD:=proc(i,N,Y)

I have done a lot of experimenting since my post of 13 hours ago and now have a better handle on the print problem. I am using an HP2110 printer. When I try to print out a document OR work sheet that I originated on maple, I click on file, select print, and on the resulting pop-up menu select properties. There are now 4 choices for print quality: Best, Normal, Everyday, and Fast Draft. If I select "Every Day" the print out will have letters (and graphs) that are twice the size that they should be. Then if I do the same exact thing, without changing anything except selecting one of the other print quality choices, the resulting print out is normal.

Does anyone know how to use "plot" for Piecewise function, wich has to set parametric function (x(t)=..., y(t)=...)? I'm sorry for my English. Thank you.

I am using maple 11. I have an HP printer which I verified is working corrrectly. I have a document made in document mode that I stored in a file, and when I print it sometimes it comes out ok and sometimes it comes out with everything about double size and I don't know what I am doing to cause the double size. When this happens I go to file, print preview and click on double page, and then single page at the top and everything seems to print ok in normal size again. But now I just completed another document and tried to print it out and it printed again with about double size letters but when I go to file print preview, double page and single page are not enabled and I don't know why and consequently I have no way to print out this document.

For double-precision ("hardware") real and complex floating-point operations on Matrices, Vectors, and Arrays Maple makes use of its external-calling mechanism to get to compiled code. A great deal of such compiled code for array operations requires what are known as Basic Linear Algebra Subprograms (BLAS). The BLAS libraries provide support not only directly for Matrix-Vector arithmetic but also indirectly in other external compiled libraries used by Statistics, ArrayTools, LinearAlgebra[Modular], etc.

Sometimes when I am browsing this site I have both Maple 10 & 11 open concurrently to see if I get similar results to the various post in both versions. Are there any potential problems in doing this? I am using a Mac (power pc) OS 10.39. Thanks, Thomas

I just created a document for a lab I'm doing and when I went to print preview all the graphs and diagrams I have are chopped off. I just typed everything and spaced it out on the space available to me in Maple (a lot because its widescreen), assuming the edges were the margins like in ms word. But now I can't print without lopping off all my diagrams and squishing everything beyond recognition. Is there a way to format my page or scale everything down to fit? I can upload the file if need be.

Hi, I am trying to plot the same vector field in two coordinates Cartesian and polar. Let's say the field in Cartesian coordinates

Good Morning (Germany anyway ;-) ), I'm preparing a class room note and want to display a simple algebraic expression _before_ it executes, like: (a^5+b^5)/(a+b) How can I ask MAPLE to just redisplay it in textbook like manner? thanks a lot for your help! Walter

In the admirable quest to make Maple better and stronger, and since so few people responded to the Suggestion to add a searchable bug database here on mapleprimes, here's another tack.

What are the fewest keystrokes that can make the TTY commandline interface of Maple 10.06 or 11 crash?

By crash I mean something like bus-error or segmentation-fault, stack-limit-exceeded, or lost-kernel-connection. I don't mean a runaway computation that simply consumes all...

Hello, i'm in need of some help. I'm searching how to use the library browser to create a module usable with with(). In fact i have to learn how to add or remove function to an existing library. And when i use the assistant, i see int the window a module and when i double click on the module i enter in it and i can see the fonction inside it. But when i add some functions in .m files the assistant add them in the root and not in the module. To express it clearly watch the figure Module And i want Module | |

I have a real polynomial, p(x). I want to know only, if it has a positive root? Is it possible to answer this question without the sturm command?

I read the help material for the roots command, but apparently don't understand it correctly. I've tried roots(x^2+x+1,I) and roots(x^2+x+1, complex) and the only thing returned is [ ]. How do I use the roots command to get complex roots? Thanks.
