I am trying to use Tables to better organize the layout of my Document mode worksheets. I have noticed two problems thus far.1) When I use the triple exclamation point icon to execute the worksheet, sometimes the code in the Table is skipped. and 2) I put a simple plot command in one cell. The plot showed up in the cell, but the grapgh also showed up twice below the Table. If I only execute the code in the cell, this does not happen. There is no hidden code. If I...

Hello! I'm in a pretty simple task but i'm really confused what command i can use!

I want maple to rewrite my 3 equations to one, where it's like Θ1 = ........

> Lar := 416;
                              416
> Iar := -45+158*cos(theta1)-416*cos(theta2);
            -45 + 158 cos(theta1) - 416 cos(theta2)

> Jar := 169+158*theta1-416*sin(theta2);
               169 + 158 theta1 - 416 sin(theta2)

I would like to set the range for a 3d plot.  For a 2d plot, I understand I can do it at the command line or by setting the axes properties after the plot's been drawn.

If I use plot3d(x*y, x=-10..10, y=-10..10) for example, how can I look at those parts of the surface for which -2 < xy < 2 for example?  I'd be happier with a command line option than a gui option but really anything would do.

many thanks!

I am trying to see what is in the startupcode file by using the Edit->Startup Code.  I know that somewhere is a command called interface(imaginaryunit=j) because it works when I restart.  I cannot even change anything because it does not show anything in the editor and nothing takes effect.

Hello,

With reference to the attached screen grab, the Maple command "algsubs" seems unable to substitute equation (6) into equation (3). I was expecting a result where Iani was expressed in terms of kH and k. What am I doing wrong?

Regards,

Ben

So im working on this question right now:

 Using “complexplot”, show all of the cube-roots of -8i (you will first have to 
find the principle cube root, convert to polar form, and then add appropriate 
propportions of 2*Pi to the argument to find all other roots, using Maple for all 
calculations).

Im going to attach my attempt to this post, all feedback is greatly appreciated and if im doing something wrong, if someone could lead me in the right direction.

Hi,

I have what I hope is an easy problem to answer. How would one go about having Maple solve a "vectorized" initial-value problem. For example,

 y'(t) =[t^2,exp(t)], y(0)=[-1,1]. Find y(t).

 Thanks!

I need maple to perform the following:

"int((1+m^2*(alpha-theta)^2*sin(theta)^2/sin(alpha)^2/alpha^2)^(1/2),theta = 0 .. alpha)"

but maple does not integrate. I have tried assuming that the term inside the square root is positive, with no result. What else can I do?

Hi!

I'm studying submanifolds of (semi)-riemannian and trying to look at some examples with Maple using it's great DifferentialGeometry package. But there's one thing I can't figure out. How can I define a pullbacked tangentbundle along the embedding map? Let me be more specific:

I have a manifold S, a manifold M and a map i: S -> M.

I realize this in Maple with: DGsetup( [...], M ); DGsetup( [...], S); i:=Transformation(S,M,[...]);

Hi there,

I have a de that I have gotten maple to solve using dsolve (y'''+2y''-11y'-12y)=48-28exp(3t). When the solution comes up however, the particular solution is in an odd form: 

(-4*exp(3*t)+(11/28)*exp(6*t)-t*exp(6*t))*exp(-3*t)

+_C1*exp(-4*t)+_C2*exp(-t)+_C3*exp(3*t)

However, the particular solution here contains part of the homogeneous solution inside of it: namely the 11/28exp(3t) term. Is there any way to run a function on my solution...

Is there anyway to get Maple to solve for a limit of integration.  every time I try Maple gives me an error.

Sorry that this may not belong here but I thought I would ask, it is interesting. 

Now I'm not asking for the winning numbers list but rather the numbers chosen by people (the thousands of non winning ticket numbers per game)  Is there a database somewhere we can access that stores the list of picked numbers?  It would be interesting to find out how randomly people pick numbers, do people flock to certain numbers more often than others?

Hi,

I have the following ODE:

dx/dtau=s-rx+x^2/(1+x^2)

Where r,s,x vary over an interval. 0<r<0.5 ; s and x any real value (positive). Our instructor wants us to numerically integrate this. He has a program available on his website but I would like to know how to do this in maple. I have the answers to the question already but I would like to use maple to find the answers. This is for a course in Nonlinear Dynamics and Chaos. I am not very proficient...

I am dissapointed. I recently upgraded to Maple 15 and I bought a license for the NAG libraries thinking that I could use NAG mark 8 chapter F12 to solve my Eigenvalue problem with large sparse matrix, in reality, there seems to be no implementation of these NAG routines in Maple. is there a way to get around this problem? I know I can also connect to MATLAB to take advantage of the integrated sparse handling but I want to avoid buying another piece of software(you know we scientist aren't millionaries).

I need a power regression function and I need it to be accurate, look what happens

> X := Vector([1, 2, 3, 4, 5, 6], datatype = float);

> Y := Vector([1, 4, 9, 16, 25, 36], datatype = float);
> PowerFit(X, Y, x);

                                            (1.9999999999999998)
      (1.0000000000000004) x                          
> f(x):=1.*x^2.;( using CTRL+L to get the result)
