I recently posted a worksheet to my blog. I used the feature in the MAPLE file manager which turns a worksheet into code so it can be displayed more or less the same way it looks in MAPLE. I copied this code and pasted it into the text of my post. When I did a preview I saw what I would refer to as the "blue equations" but for the equations I actually typed into the worksheet at the MAPLE prompt, I only got boxes which said "Maple equation". When I click on these boxes nothing happens. So someone would really have to open my worksheet to get any sense of what I was talking about, which was not what I intended. I don't recall running into this problem before. Maybe I am doing something different than before and just don't know it. I would appreciate any suggestions.

Hi Our university (Univ. Sao Paulo - Brazil) has license for maple 9 (not sure which release).. It can be also that the version they have is Maple 6 since there is a xmaple6 in the files (see bellow) I use in my machine Ubuntu linux, the newest version. Althoug it says it has linux support for maple, nobody was able to install it from the instructions provided from above to us, users. I will describe the situation: we get from the university a tar file containing the files root@edf:/etc/Maple/bin.IBM_INTEL_LINUX_REDHAT# ls -1 hostpatch ld-linux.so.2 libc.so.6 libdl.so.2 libICE.so.6

Hi I got an equation that I would like to find out its turning points.As you know you first have to differentiate it and then..... Here is my command on maple: y:=x->6x^2-7x-3*exp(-1/5*x); df:=diff(y(x),x); solve(%,x); and then I get 5 LambertW(-1/100 (e)^(((-7)/60)))+7/12 5 LambertW(-1,-1/100 (e)^(((-7)/60)))+7/12 as answers, I don't know if they are correct, but I do know that there must be a simpler answer than this! I was therefore wondering if you guys know how I can approach this problem differently! Thanks Chris

I am currently running a Maple T.A. Homework Assignment for approximately 300 students. For the fitst time, I have included some "sketch" questions, but they are giving many many problems. I instructed students how to download, install and enable Java if necessary, but the problem is persistent, so much that I suspect it is not the students fault. Of some of them at least I know their settings seem fine. Is there a known problem with Java 1.5.0_09, which is what they get from download? Any help is appreciated, also info about what questions I should ask them to find out where the problem is: I

I wish to know if there is way to plot the following functions: x1=X1+X2*gamma(t) x2=X2 and x1=alpha*cons(theta)*X1-beta*sin(theta)*X2+gamma x2=alpha*sin(theta)*X1-beta*cos(theta)*X2+gamma where in the second one alpha, beta. and gamma are constants. many thanks, A.

Hi, At my university i saw a presentation of maple. It was running under linux (kde), and obviously it had a (Trolltech) Qt GUI. I really would like to work under a Qt-GUI, too, but I have no idea how to do that. The only GUI I get to work is the normal Swing-GUI of the Java Version. Thanks a lot, David

I'm having problems plotting the derivative of a function after I've solved the ODE in an ODE system. Any help appreciated! The MAPLE help for plots,odeplot says: "Multiple curves can be plotted by specifying a nested list format. For example, [[x,y(x)],[x,diff(y(x),x)]] displays the dependent variable and its derivative as a function of x on the same plot." So, here's my problem. I define mtest with my two ODE's and two initial values, and solve it numerically over my specified range. This works great. mtest := [diff(m(t), t) = -43/25*exp(-8527.784461/(pt(t)+273.15)+19.03523317)*(m(t)-exp(-23300/(8.314*pt(t)+2270.96910)+2.646139043)), diff(pt(t), t) = 240, m(0) = 1, pt(0) = 105];

How do I change the spacing between lines in the MathMLViewer?

Hello, I would like to do some computations with Legendre polynomials. I would like to know, if Maple is able to do some simplifications and use orthogonality of Legendre polynomials. For example > Int(LegendreP(m,x)*LegendreP(n, x), x=-1..1); This integral should be zero or 2/(2*n+1), depending on the relation between m and n. Is there any chance to get it (maybe using the procedure assume() )? another example: > diff(LegendreP(n,x), x$n); This should be (2*n)! Thank you very much for your help. Karel Srot

I have defined a function in a parameter form x:= .... y:= .... and I have defined a circle in a parameter form X:= .... Y:= .... Now I want to calculate the intersectionpoints. I could use: solve(x=X,t) and solve (y=Y,t) but the teacher teached me that some points are going lost if you use to separate commando's. Now is the question what's the commando for combining these two solves. My concrete example: restart:x:=2*cos(t)+cos(2*t); x := 2 cos(t) + cos(2 t) > y:=2*sin(t)-sin(2*t); > y := 2 sin(t) - sin(2 t) Circle:

I'm aware that this probably is not the right place to post this, but is there anybody who can do something about brownstone.net being unreachable? I have to convert a BIG LaTeX-file this weekend for students to work on starting Monday and have been unable to connect for the past twelve hours or so.

Hi, I have a system of 3 coupled equations (3 unknowns) with complex numbers. I solved them with solvefor. I'm interested in the modulus (|a+ib|^2 = a^2 + b^2 ) and phase of each solution. Because of that I used polar and abs (I have more interest in the modulus). In each case I ran simplify, despite of that the solutions are huge. I would like to work with them in some spreadsheet (in order to set the parameters, evaluate the solutions, compare them with some experimental data and do some plotting). Given that the solutions are huge I can just write them by hand where I want. In order to automatize that I've tried to use the VisualBasic command to cut&paste the formulas in VBA. The problem is that they are so long that the source code just gets broken.

Hi I'm currently doing a maple assignment for my uni course, and was wondering how do you simplify this equation to get a simple quadratic! 6x^2-7x-3*exp(-1/5*x) as you can see its really a simple quadratic with an exponential stuck on to it! My question is can you simplify it with maple, 2.) Does the whole equation only have 1 root since its an exponential function stuck on! Thanks Chris

So I went ahead with alec's timer code and expanded on that, his window approach was also the approach I would need to furthar push the project to completion, so the beginning is pretty much his code, and works plenty fine. Now I was working on the project and then realized in order to set things up the way I want, i'm going to have to make a grid layout, also suggested by a fine coder here in a previous help topic, now my problem is, I had to rehaul ALL of my code to use grid layout, grid layout seems like a really easy to use system, and I started converting all the code to comply with that, and in the huge mess of brackets and square brackets, I seem to have messed up the overall opening and closing of said brackets.

How do I plot a prism or a general polyhedron with maple ? I tried polygonplot3d but the result is not satisfactory because maple does not recognize the edges between the faces correctly. Thank you very much for your answer.
