For MathieuA and MAthieuB:

Values returned by MathieuA  and MathieuB are characteristic values  of the corresponding Mathieu function only when v  is a rational number and MathieuA  and MathieuB  return a different number only when  v  is an integer.

You can see a plot on maple pages for a0, a1,.. a4. And b1, b2,..., b5.

However, I would like to plot characteristic values for non-integer values. I would like to do this...

I have to plot a variable in a diagram which is updating itself. The Variable is the area of a various triangle and the  value has to be plotet in a view of the triangle. How to do this? 

Is there any way to reverse an axis in the plot command? I solved the baristochrone problem as 

a school project,but I did it using an upside-down Y axis. Of course, when I try to make a graph with

my solution, I'm getting a regular cycloid instead of an inverted one, since I was using a 

reverted Y axis when solving the problem. 

Help would be very appreciated as I couldn,t find anything on the subject.

How would one set up a multispring model in maplesim?

Actually I don't know the exact model I want to try to explore yet, but I was wondering if someone could show an example of, let's say a beam with 4 springs attached offset to one end.  On one end of the beam we inject vibrational frequencies and graph the output on the other end - doesn't matter which end - I imagine we could explore both from both ends.  How could we set that up?

Here is my example picture.

I've been trying to work out an algebraic expression for the following summation

, entered as S[n,t]:=sum(f,k=0..n-1); (with f:=k!/(k+t)!;)

I entered the above Maple expression into Maple (13) just so I could check out some small example summations I had. Maple's arithmetic, accuracy and speed is much superior to mine!...

How would I create an interactive component similar to the Locator functionality provided in Mathematica? For example, the command in Mathematica

Manipulate[
  Graphics[Polygon[pt], PlotRange -> 2],
  {{pt, {{0, 0}, {1, 0}, {1, 1}, {0, 1}, {1, -1}}}, Locator}
]

creates five Locator objects stored in the variable pt. This example can be found in the

i'm writing this program and for some reasons i got this error, here is my code

maplet_error.mw

evaluating `"myadd(1)"` produces the error: invalid input: myadd uses a 2nd argument, n, which is missing.

the second question is that my procedure only calculate any integer number from 0 to 9 , is there anyway to get this procedure

to calculate bigger...

Hi there,

I have created an animated plot of a modelled beam under sinusoidal forcing. It shows the beam bending along the x-axis. I was wondering how to plot the animated function with the beam lying along the y-axis instead of the x-axis as happens when i use the following command:

animate(w,x=0..1,t=0..0.1,frames=150,numpoints=100,color=red,thickness=3);

Any idea's?

Dear friends

I want to plot a function with these coordinates in x and y directions where:

x=(0,0.0150754,0.0376884,0.0829146,0.0527638,0.120603,0.173367,0.203518,0.241206,0.286432,

and

y=(1, 1.20603, 1.53769, 1.6, 1.77889, 2.74372, 3.49749, 3.9196, 4.43216,...

Hello!  I am writing a Grassmann multiplication operator:

define('`&*`', 'multilinear', 'flat', 'identity' = 1)

So that it automatically constructs operators like &*(arg1, arg2,arg3 ...)

Now I want to teach Maple how to transforms &* with ARBITRARY number of arguments.

How to create a pattern for that?  (to be added to "define")

hi all, my knowledge of maple is quite limited and i havent used it in a few years so perhaps some of you can show me where ive messed up. I keep getting this error:

Dear guys

To solve a typical integral I have written

int((t^(f-3/2))*(1-t^(2*(f-1)))^(-1/4),t);

but the solution is very complicated and contains "hypergeom". How can I have a simpler solution? I mean an explicit solution.

Thanks.  

Hi every one, plz can anyone solve these equations numericallly by maple:

Dear All,

I am trying to find (complex) eigenvalues and eigenvectors of a matrix as a function of a variable. Using the following commands lead to the respective errors:

- LinearAlgebra[Eigenvalues](A): Error, (in content/polynom) general case of floats not handled

- LinearAlgebra[Eigenvectors](A): Error, (in LA_Main:-Eigenvectors) cannot determine if this expression is true or false: 0.2480392156e-4*abs...

Can anyone explain these results?  I m trying to check on a more complicated form of this expression, but cannot proceed without understanding what is occurring in this case.
