Hi, I use maple 10 under linux (red hat). In a file ABO.mw I have created a module that has a structure like: Mymodule := module() description \"procedures for Quantum Mechanics\"; export DP, deltaK; option package DP:= proc(...) etc,etc end proc; deltaK:=proc(..), etc, etc end proc; end module; When I execute the group and then type: with(Mymodule); the procedures appear. I would like a library containing this module to be automatically loaded upon startup so I can call it with with(Mymodule); whenever I start a new worksheet.

Hi there, I'm trying to integrate some experimental data. I'm sure that what I'm doing is not the best or most convenient way, but I think it should work. I read the data in using the import assistant, which put it into a 2d matrix. I then manipulated that matrix. This is heat capacity data (for those of you familiar with physical chemistry), and I'm baselining the h.c. data to zero before I integrate it. This hasn't presented any problems for me, and it (seems to) give the expected result. When I integrate this baselined data, however, the integrated curve (enthalpy) at low values of x is not close to zero; it is much bigger. The integrated curve's topology is what I'd expect, it is horizontal at small x values. It is just off of zero by some (large) constant. My data starts at about 300, ends at 360.

How do it find fibonacci prime numbers using Maple?

Okay, I know Maple's not giving the wrong answer...I'm sure I'm just asking the wrong way. When I ask for the standard deviation (Statistics:StandardDeviation) of a list of individual data samples, I get the expected answer. However, when I provide a list of values and a list of frequencies, I don't get the answer I'm expecting. Hopefully the attached worksheet will make my problem obvious.

Hi, I'm trying to set my MathML viewer to update constantly, as a certain animation in a plot changes. I would either need some type of "time delay" device since the animation works by millisecond delays (which I am able to control), or some type of animating function that isn't for plots, but for procedures. Basically, I am looking for a way to use Set or SetOption over and over again, at specific intervals, without having to click a button or perform a certain action each time the option changes. Thanks for any help.

Is there any way to plot more than one pointset on the same graph using pointplot. On my worksheet the following worked plotpoint(points,color=red); plotpoint(points2,color = blue); But not plotpoint({points,points2},color = [red,blue]); or plotpoint([points,points2],color = [red,blue]); Any suggestions?

ok me again, I have this economic problem. Dc( pc , pt ) = 2000+1000*pt-2*pc Sc (pc) = 23*pc how can I plot this, and If I don't know what the value of (pt), can I still plot this? thank you so very much in advance.

how do I find the value of (p) that will make an equation equal to an other. ex: D(p):=82-0.75*p and S(p):=1.3*p how do I make maple find the answer. ( I know its way more easy by hand, but I would still like to know). thank you ! Jp

I'm just trying to draw a Petersen graph with one vertex removed, using Maple 10: with(networks): P:=petersen(): Q:=duplicate(P); delete(1,Q): draw(Q); I don't see anything wrong with these commands, and yet I get an error message: "Error, (in draw/concentric) not a list of vertices [1,2,3,4,5]" Yes, I know that - I've just deleted vertex 1. But surely I should still be able to draw the resulting graph? I know I can fiddle about with "Concentric", but I don't want to... And another thing: the inplace implementation of "delete" is, I think, contrary to reason. I would rather have:

Does anyone know how to draw a triangle in 3 space with three points? Also, I need to plot 3 vectors on the same graph. Thanks

Dear All, I'm working on a problem in differential equations where I need to compute the n-th power of a differential expression. Can Maple be taught to differentiate polynomial functions without carrying out the multiplications / simplifications that it usually does? For example: diff(-2*c/x^3,x); gives the answer 6*c/x^4. I want it to return: (-3)(-2)*c/x^4. Ideally, I also do not want it to simplify sums of such results. Thank you very much, I appreciate your help! Andrea Bruder

Okay, well...we're using maple for our math lab in our school and we tried to work on our project. We had this matrix: A := RTABLE(419945880,MATRIX([[a, a, a, a], [0, 0, 0, b], [0, c, 0, 0], [d, 0, 0, 0]]),Matrix) And when we tried to get the inverse, it would just lazily respond: Inverse(RTABLE(419945880,MATRIX([[a, a, a, a], [0, 0, 0, b], [0, c, 0, 0], [d, 0, 0, 0]]),Matrix)) And it's been working like that for other matrixes, I don't know if I need to configure maple in a different way or something...?

I am working on a project in Maple 10 that was originally designed for Maple 9.5. I am trying to define the weighting function wt. The problem is that the instructions say to type the following command line: wt := n -> if n=0 then 1 elif n=NInts then 1 else 2 end if; However, when I do, the following error message shows up with the phrase "n -> if" highlighted in a red box. "Error, invalid inline function wt := n ->if n=0 then 1 elif n=NInts then 1 else 2 end if;" Thank you for your help. Adam

I wish to factor the following: r^4 +10*r^2 +9*r = 0 I have entered it in Maple 10 as: factor(r^4 +10*r^2 +9*r); and I just get a repeat: response: r^4 +10*r^2 +9*r Am I doing something wrong or can not Maple factor this? I'm fairly new to Maple. Any help would be appreciated Larry Ciak aka malt_master@comcast.net

First Question: Let's say I have just created a plot using the Interactive Plot Builder. What If I just want to tweak the expression in the plot. Is there any way I can get the Interactive Plot Builder to open with all of the info related to a specific plot already inside the plot builder, so that I could just tweak the expression and everything else would remain the same? In other words, is there any way around having to start from scratch with the Interactive Plot Builder? A related question is this: Assume there is a plot, created with the IPB, in your worksheet. Is there any way to click on this plot and find out what Maple commands would have created the plot if the user had done it that way instead of using the IPB?
