Hey there

Is it possible to to view A4 paper when you work in maple instead off the "endlessly big" sheet you work in as standard?

My problem is that when i work in maple, it look different when i print it too an A4 sheet.

Looking forward to hear from you :)

Consider the following function defined as an integral with parameters:

f:=a->int(a*x,x=0..1);

If one tells Maple to integrate this function int(f(x),x=0..1); evaluates to 1/3 although the correct answer would  be 1/4. This is because for Maple f(x)=int(x^2,x=0..1). (Isn't this quite a serious bug?) If one would rename one of the variables, the evaluation would work. My problem is that I want to define a sequence of functions...

How do I allow an infinite amount of parameters (...rest parameters don't seem to exist in Maple) such as the ones in the piecewise procedure (except for the optional parameter)?

first, thank you for reminding me, acer.

2nd, I received a mail that someone posted a new comment, but now I can't find my post, where is it?

3rd, can someone tell me how to ask an old question if no one answers for that question?

thank you in advance.

my old question is here:

I  Presented problems for the plot "DB magnitude spectrum."
The structure of vector data spec has the following configuration,Float (-infinity), inside.

N := 64;
T := 1;

f := .25;
A := 1;
phi := 0;
n := Vector(N, -> i-1, datatype = complex[8]);

x := cos~(2*Pi*n*f*T);

X := DiscreteTransforms[FourierTransform](x, normalization = none);...

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,[...]);

There...

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...
