I am trying to familiarize myself with the functionality of the Maplet Builder, and I'm having some frustrating problems. Whenever I set a button to change the value of a MathML viewer, for the command, I use the statement MathML[Export](insert Maple statement here), and I receive an argument error. In addition, I was wondering if (while using the builder) there was a way to add some code that evaluates one or more Maple statements (i.e., variable definitions to be used by multiple Maplet components,etc.) that does not affect the value of any of the component properties. I'm used to using the GUI components in worksheet mode which seem to be more flexible in terms of programming actions for components (perhaps only because of my ignorance pertaining to the Maplet builder).

hi; i have a system of 4 equations depending on each other, which cannot be solved explicitly. using the fsolve command reports a solution, however there must be whole bunch of possible quadruples. i tried to fit the fsolve command in a loop, ignoring the previous solutions, without any success. can anybody give me a hint on how to come up with the whole range of possible solution?

Dear all, I evaluate a multiple integral (need to do 6 times). Maple cannot find analytical solution, so i try numerical as follows. But it still dind't give me a solution. Why? Is it because the function is too complex and too many integral? Thanks a lot! R := 250; l := 1500; e := 2000; n := 5; a := 100; alpha := 2000; beta := 2000; h := (x,y,s,t,u,v)->(1/(pi*n*(a^2)))^3 * exp(-(1/(n*(a^2))*((x-alpha)^2+(y-beta)^2+(s-x)^2+(t-y)^2+(u-s)^2+(v-t)^2))); Int(Int(Int(Int(Int(Int(h(x,y,s,t,u,v),x=0..2*R),y=0..l),s=e..2*R+e),t=0..l),u=2*e..2*R+2*e),v=0..l); evalf(%);

When I try to get online help for the optimization package by executing the command: ?Optimization I do not any information on the package at all. The info seems to be missing entirely. For example there is no online info on the LSSolve function. Where is this info hidden? I'm using 10.04 (Mac). Thanks.

Hire There: I am trying to make a contourplot animation of the function u(x,y,t)=exp(-Pi*Pi*t)*sin(2*Pi*x)*sin(2*Pi*y),defined in [0,1]X[0,1] I tried this a := proc (t) densityplot(proc (x, y) options operator, arrow; exp((-1)*Pi*Pi*t)*sin(2*Pi*x)*sin(2*Pi*y) end proc, 0 .. 1, 0 .. 1, axes = frame, style = PATCHNOGRID, colorstyle = HUE, numpoints = 6400) end proc display(seq(a(t), t = 0 .. 1), insequence = true, axes = framed); but it seems that it is not working I really appreciate your help

Can anybody tell me, How to use Dirac Matrices (Direct products of Pauli Matrices) in Maple?

I would like to define J=(y1-y10)^2+(y2-Y20)^2+k*(u1)^2+k*(u2)^2 where y1 is a function of u1 and u2 y2 is a function of u1 and u2 then I need to diff(J,u1), diff(J,u1,u2) Thank you for your support Don

Hi guys, I am trying to integrate the following expression: u_ratio:=(4/omega_star)*(sin(omega*t)-(exp(-B)/sqrt(r_star))*sin(omega*t-B)); where omega_star:=omega*r0^2/nu; r_star:=r/r0; B:=(1-r_star)*(sqrt(omega_star/2)); I would like to obtain integral of u_ratio with respect to r_star, and separately the integral of u_ratio over one period. When i try to use something like int(u_ratio,r_star) in only get back a large expression with an integral symbol still in it. What would be the best way to approach integrating this guy? Thanks, Randy

How to finding alpha(n) of this system equation finding alpha(n) whan n=1..3 cos(alpha(1))+cos(alpha(2))+cos(alpha(3))=3*pi/4; cos(5*alpha(1))+cos(5*alpha(2))+cos(5*alpha(3))=0; cos(7*alpha(1))+cos(7*alpha(2))+cos(7*alpha(3))=0; so.. i am basic maple user.herry herry.

After some experimenting I found that using AXESTICKS forced the use of POINTS (more or less) and PLOT. The problem is that I would like to draw a line instead of points.
I am trying to generate normal probability plots to be used for comparing different cases.

First time posting here, hoping to find some help, and I may try to help others. I have a set of 8 equations. Each of the 8 equations are in terms of two variables. For example: x1 = f1(theta1, theta2) x2 = f2(theta1, theta2) x3 = f3(theta1, theta2) x4 = f4(theta1, theta2) y1 = f5(theta1, theta2) y2 = f6(theta1, theta2) y3 = f7(theta1, theta2) y4 = f8(theta1, theta2) the functions f_j are not neccesarily linear and are fairly complicated with many factors. I need to remove (eliminate) the theta1 and theta2 terms from the set and be left with a new set of equations that is in terms of x_i and y_i.

Hi all: I want to realize the following function in maple: 1> According to the input vector, n, canculate the n times of auto-convolutions, after getting the final result, measuring the vector according to each element of the result. If I use the math language, Suppose I have vector, called A the length of vector is L; Result = A*A*....A (n times convolution); Measure= Sum (on i) (Result[i]*ln(Result[i]); I donot know how to coding like that Thanks for any help. How to read the parameters from keyboard in maple? Thanks bin

I wasn't sure of the details of non-Maple-owners accessing Maple content via MaplePrimes. Do they have to be members of MaplePrimes (can non-Maple-owners be members of MaplePrimes?) Either way, where can they go to access the content? I understand how to upload and access my own content via the file manager, but I don't understand how it can be made available to and viewed by others. Thanks a lot.

I am trying to compute some Lie brackets in Maple but am having trouble with the output. The first five few terms that I computed are small enough that they will display with pretty print. However, the sixth term gave me the error 'Large output of more than 1000000 nodes' and it couldn't display. I turned pretty print off and eventually got it to display the sixth term but now I can't get the seventh or eighth terms to display even with pretty print off. Every time I try to output the expression for the seventh or eighth Lie bracket Maple just stalls out. Since it can compute the terms that I need but not display them is there a way I can export the hidden content to a text file or some other format so I can copy and paste the equations into Matlab?

Hello everybody: I need to know how to export or create a plot directly into a data file (i. e. .dat or .csv) to pick it up with Origin or something like that. Thanks, L.
