My goal is to find a way to code sliders that set parameters for a plot so that it is not necessary to re-code all of the existing sliders when a new one controlling the same plot is added.

The closest I've come is the following.   Say I've defined a couple of functions

f:= (A,x) ->  sin(A*x);

g := (B,x) -> cos(B*x);

and

plot0 := plot([f(A,x),g(B,x)],x=a..b,color[blue,red]);  

And two sliders with code for action

I want to use the Bits package, but have troubles - may be a bug?

I do not understand the following (Maple 15), where the help says "The And
command computes the bit-wise logical and of the inputs ... "

  with(Bits);
  Settings(defaultbits=4); # poor help text for that ...

  4; Split(%);

Hello.i want animate the circle of radius 2 on the parabola y=x^2-30*x in the interval [-1,2].I wrote like that =animate(plot,[[-30*t+2cos(Phi),t^2+2sin(Phi)],Phi=0..2*Pi],t=-2..1) .But it doesn't work.What is wrong?

How do I slection input and output in a Maple procedure?

Hi all,

first off, I don't think this is a normal "how do you rescale a graph" question - I'm aware that there are plenty of those around, but none seems to answer my question.

I essentially want to change the x-axis of a graph by a factor, rather than just changing the plotting range or tick-marks. For example, I have a function, f(x), and it's derivative (with respect to x) f'(x). I can plot f'(x) for x=1....60 easily for example, but I also want to plot f'(x...

This is something simple but I cannot find the answer

Typing in
a:=5;
gives the maple output
                                      a:=5

I have changed a setting somewhere so that Maple doesn't show the assignment

When I type
a:=5;
Maple returns just
 ...

Hi there,

I am plotting flow diagrams of a 2-dimensional system of autonomous 1st order ODEs x'=f(x). I have some free parameters in there, and am analyzing how the flow changes qualitatively when varying these.

To visualise my results I want to do some animations. The Explore command doesn't seem to like the DEplot command, or I am doing something wrong. So I use the animate command, which works fine, although I can only vary a single parameter with it.

Dear Maple-experts,

is there a function which returns the linear parts of an ODE?

So for example for the ODE:

ODE:= diff(x(t),t) + 3*x(t) + diff(x(t),t)*x(t)

which gives

diff(x(t),t) + 3*x(t).

My ODE is so large, that this cannot be done by hand.

Thank you very much,

Peter

I want to calculate  an eigenvector of a jacobian matrix J with fixed parameters from the solution of some equations, but the following code does not work. When I use the command in the last 3rd line, it works well.
But I want Maple to calculate J automatically, what shall I do?

restart;
with(linalg);

F[1] := A-(B+1)*X[1]+X[1]^2*X[2];
F[2] := B*X[1]-X[1]^2*X[2];

J := jacobian([F[1], F[2]], [X[1], X[2]]);

sol := solve({F[1] = 0, F[2...

Hi, I am currently trying to draw a standard airfoil NACA 4412 (http://en.wikipedia.org/wiki/NACA_airfoil). I've put all the equations and defined the parameters.

I don't know what is the problem, probably many Float undefined errors... According to me, it should be simple, but somehow I can't get it right. Any suggestions?

Thanks

Substituting Periodic Fourier series expansion equation with standing wave equation

I would like to know how to program this equation in MAPLE to iterate and derive my results (values of "h") in the form of plots....

I would like someone to take a look at my equation and tell me if its solvable...coz am not able to graduate!!!! :(

Hi there,

Often an expression has more than one output, for example, when simply more solutions exist: sol1, sol2, ...

Then I would get the second solution by %[2]. So far so good.

Anyway sometimes the output is splited in cases, with the { notation. How do I read out a specific case of such a solution?

thx :)

Error, (in LinearAlgebra:-LA_Main:-MatrixInverse) singular matrix

what does this mean?

I have 2 equations that are made up of various powers of 2 different variables. Is there any command to retain only terms of the first order? E.g. no "x^2", "x^{3/2}", etc, just "x"s.
