Can I create an tensor in the Physics package in Maple 16 with a free index like i=1..N:

A[mu,1]:=A[mu]

A[mu,2]:=B[mu]

.

.

.

and so on? The index is not one of the type gauge, spacetime or spinor.

Can you expalin the difference between the gaugeindices, spinorindices,and spacetimeindices in the Physics package in Maple 16? 

Hello every one,

I am using similarity transformation to transform a PDE into an ODE.

I got the ode but its in a very ambiguous (unclear) form.

I need help to have the ode in a more friendly reading format.

Thanks

Is it possible to change the caption of RiemannSum command in Student[Calculus1] package with animation output option, keeping approximate value and number of partitions outputs?  I tried to use typeset command, but I haven’t succeeded.

Hi, I have created 2 annulus;

> display(sector([2, -5.5], 2.5 .. 3.5, (1/5)*Pi .. (1/2)*Pi, color = "Niagara Burgundy"), axes = none, scaling = constrained);
%;

> display(sector([5, -5], 1 .. 1.5, (1/5)*Pi .. 2*Pi, color = "Green"), axes = none);

But I want the green annulus to cross the Niagara Burgundy annulus at the points where the green annulus is open. The green annulus is open with an angle...

Hi,

I have succesfully created a annulus. Because I am creating a garden, I am interested in making circular shrubs in the annulus. I mean an annulus filled with small circles.  How do I do that?

I have this annulus;

display(sector([4.5, -5.5], 2.5 .. 3.5, 0 .. 2*Pi, color = "Green"), axes = none, scaling = constrained)

the radius of the small circles should be: (3.5-2.5=1)

I am trying to write out a code to solve for current in a LRC circuit. I have written a code that I think is capable of doing this but keep getting a recursive assignment message in my for loop. I have looked it over about a hundred times and can't see where I have defined a variable in terms of itself. Any help on this would be greatly appreciated. A copy of my code so far is listed below.

Hey all,

Just started using maple for one of my university courses and am having some problems trying to implicity differentiate a question in one of the problem sheets I have to do.

I am trying to find y' for cos(exp(xy)) = x and the command:

implicitdiff(x = cos(e^xy), y, x)

results in a FAIL. Am I doing something wrong?

Thanks!

Hi,

I'd like to verify the Routh-Hurwitz criteria for a 5th degree polynomial. For the last condition, maple computed the quantity. However when I want to expand (with the commands expand or simplify) this expression (in order to check it sign), maple can no longer display it. In fact Maple calculated the expression but cannot display because when I put a colon in front a the expression, it's okay. So I'm looking a way to display those this result. By the way it's a expression with 43302 terms.

Hi all,

I have this small code as example:

> restart:with(LinearAlgebra):
> e1:=5*x1-x2+6*x3+10*x4-10;

                 e1 := 5 x1 - x2 + 6 x3 + 10 x4 - 10

> e2:=x1-x2+x3-10*x4;

                      e2 := x1 - x2 + x3 - 10 x4

> e3:=2*x1+3*x2-8*x3-x4+20;

Hi,

I need to know how I can obtain a curve with different color. I work with Maple 15

I have a function like this:

Plot (C1, C2, C3, t=1..200, color= red, green, dark)

where C1, C2, C3 are mathematic function and t is the time because these function depend of time.

I need to know where the curve is obtained how can I know that the color green correspond to the second function?

Thanks you in advances.

Hi, I am creating a garden with plan view   in Maple. 

I want to create a train in my garden, so i need to create 1/4 annulus. How do I make that?

Hi, 

How can I create a rectangle in Maple knowing 4 points?

> with(geometry);
> point(A, 0, 0); point(B, 0, -15);
print(`output redirected...`); # input placeholder
                               B
> line(facade, [A, B]);
print(`output redirected...`); # input placeholder
                             facade
> point(C, -3, 0); point(d, -3, -15);
print(`output redirected...`); # input placeholder
                               d

I have a HOMEUSE licence including Maple 15, MapleSim 5, with Driveline and Tyre Libraries. Does anyone know when the intergated Maple 16 / MapleSim 6 will be release for upgrade?
