I have two IVP ODE's that i can find the approximate solutions of but I cant figure out how to plot them correctly

for the first one i have tried this..

it needs to be plotted on the interval [1,4]

I am happy to let you know that we have just released Maple 14 and MapleSim 4.

Maple 14 provides access to the new MapleCloud Document Exchange, which gives you an easy way to share your work with your colleagues, your students, and the entire Maple community. Other new features include more mathematics for engineering applications; performance improvements; the Maple Toolbox for MATLAB®, which is now included with Maple 14; a new numerical differential equations solver, the Cash-Karp pair; an enhanced point probe for 2-D plots; more task templates; and the ability to execute Maple documents programmatically. To name a few. See What’s New in Maple 14 for more information, and to watch a movie about the MapleCloud.

MapleSim 4 comes with a new 3-D construction environment for multibody modeling, which lets you build, visualization, and interact with a 3-D representation of your model. It also provides flexible probe management tools, a new semi-stiff solver, new components, and an enhanced Project Manager feature which organizes subsystems, probes, and attachments. For the full list, and to see a movie showing the new 3-D construction environment, see What’s New in MapleSim 4.

Objective: plot a graph from data drawn from two arrays. I would like to have the data points marked with a symbol (point, circle, or diamond, etc.) on the graph. How do I do that? Following is the code: -- two arrays of data point: engineeringStress and epsilon(engineering strain) -- Zip is used to put two arrays into data points (x,y) to create stressStrainData -- plot is used to graph The plot shows a line; I would like to have the data points marked (visibly seen) on the graph. Thanks. --mdc > restart; > with(plots); with(plottools);
I would like to calculate engineering stress using array; but the following piece of codes do not seem to work. *EngineeringStress = force / area *Define force is an array of measurements of force. crossArea:= 3.2 * 19.1 (not the "*" is really a "." in Maple editor; it is multiplication) force := array ([0., 1380.0, 2780.0, 5630.0]) engineeringStress := force/crossArea; engineeringStress[1] ({0., 1380.0, 2780.0, 5630.0}/crossArea)[1] it suppose to be 0!!!

i have two quotes :


You confuse science with engineering, publication with patents. Intellectual property law does not recognize ownership of scientific truth. Your theory is true, or it isn't. You don't 'own' it. An apple does not need Isaac Newton's permission to fall to the ground. The primary protections for inventions are trade secret and patents. The primary protection for other intellectual property is copyright, and wise choices in how you use it and publish it.

Maplesoft has just released a collection of new engineering products, including MapleSim 3, the latest version of our physical modeling tool. It includes a new hydraulics library, more electrical machines and improved solvers which expand the scope of models it can handle. It also comes with a new project manager, more diagnostic tools, a 3-D visualization preview feature, and other improvements to the interface which reduce the development time. See What’s New in MapleSim 3 for details.

This week I decided to do some research and find out the details of how to make model animations with MapleSim, by adding in CAD drawing files of the component parts. To see what I mean, take a look at this quick animated movie that shows a robot arm with five degrees of freedom:

So MapleSoft has sold out to a Japanese engineering company. I have lost all hope that the company will ever care about mathematicians again.

It used to. But for years it has all been about engineering. The new features that mathematicians care about get fewer every year. All R&D seems to be on the MapleSim, Matlab integration etc or interface.

Hi there,

My name is Sasi Bhushan Beera. I am Graduate Student in Mechancal engineering at UB.

I have been working on dynamics of mechanical systems for my research. What I intended to do

was to obtain equations of motion using MapleSim and copy paste them in a seperate document

folder and solve them numerically. Considering the case of a Simple pendulum, I was successful

in doing all this but I had problems with animation of the pendulum.I need some help with the animation

          I am a student, Faculty of engineering, computer systems department, my field of study as Theoretical and modeling by using Maple. I have more difficult to solve the system of differential equations . I need any help from you by any way you could suggest. ( you can change the initial conditions to get the primary solution). I try by many methods but i can get any solutions.

dB1(z)/dz= - a.B1(z) – (g/AE). B4(z). B1(z)
dB2(z)/dz= +a.B2(z) + (g/AE). B3(z). B2(z)

As a follow up to the original announcement, I thought I’d include a few more details on some of the new features in Maple 13 designed for engineers. For more information, visit the What’s New pages for professionals and for engineering education.

Maple's package DiscreteTransforms is a bit skinny, I miss various ones like discrete cosine transforms (at least the most 4 types), sine transform, Hartley transform, z-transform and may be the fractional Fourier transform or symmetric FTs (not sure for the whole herd).

It should be available, if Maple wants to be a numerical tool for technical users (all kinds of engineering I would say): it would not make sense for them to use other libraries, compile and finally combine with Maple, because it does not have it.

Is there somewhere in maple where I can find a list of math, physics, engineering formula's?

I'm actually a little surprised maple doesn't have a math formula, physics formula, engineering formula etc...  help pages or something.  Just a list of formulas, like the cosine law, maxwells equations, bernoulis principle etc... or even simple formulas.  That one could reference to. 

It should be fairly easy thing to make, no? 


For structural engineering problems, when I multiply a force (N) by a distance I generally want the answer in (Nmm) or (kNm) or units of that form.  Yet Maple simplifies the result to Joules, which doesn't mean a whole lot to me when I'm trying to find stresses and strains in structural members.

My question is, how can I define my own set of units that I'm comfortable with instead of having to accept the default Maple units?  I'm not having a lot of success customising units with Maple.

GMP is now deeply integrated into Maple - which I consider to be a good thing.  But it appears that compiler writers are doing a bad job (see the first paragraph on GMP's home page)  In other words, unless you carefully make sure that you have compile GMP properly, it is entirely possible that you end up with a buggy library.  Very scary stuff.
