Hi im using maple 16 and defined a vector field that is lengthy below,

(and yes i defined with(VectorCalculus), and SetCoordinates(cartesian(x,y,z)) (x,y,z is subscripted)

And i am using a type of line integral for the work of a particle's path through a force field which i defined here as Z.

Hello,

I'm trying to fit some of my research data to a polynomial.   I can do this, but what I need to know is how Maple is calculating the standard errors.  In other words. I need to know the underlying forumla Maple is using for these standard errors.

Is there any documentation on this anywhere?  

For reference, the Maple command I am using is:
LinearFit([Z^(-2),Z^(-3),Z^(-4),Z^(-5),Z^(-6),Z^(-7),Z^(-8),Z^(-9)],X,P2,Z,output=standarderrors);

Has anyone seen this form of a nonlinear equation with respect to X, but linear with respect to Y & Z?  I provided a contour plot within the region for all 3 variables between -2 & 2.  The plot is actually Z*conjugate(Z) so that the magnitude is above ZERO.  If I am correct I may have seen this before in orbital mechanics, but my undergrad years are a bit...

H(M) = ker(d_k) / im(d_k-1)

would like to see the example of calculation of H(M) above

I am experimenting with the new AS3 flash questions and everything works as expected except that I cannot load external swf files using a xml file. I have a parent swf file that behaves well, except that this parent swf cannot load the external swf files. It works flawlessly on my own website (which even does not have a cross-domain.xml file in the root directory).

Is there a restriction in Maple T.A. that prevents loading xml files by a swf (and/or loading external swf's in general)?

eqn := y^2 = x^3 + a*x  + b

where a and b are summation of things, or constant

if use convert(eqn, ratpoly) to get a ratpoly

can it be used to guess gf using guessgf directly?

or

convert ratpoly to differential equation and then calculate eigenfunction and calculate generating function?

I'm not sure if u have seen this website http://mathproblems.info/working.php#s99 but i wonder if there is a better way to solve this problem using maple:

It is your task to deliever as much grain as possible from city A to city B. The cities are 1,000 miles apart. You initially have 10,000 pounds of grain. Your camel may carry up to 1,000 pounds and eats 1 pound of grain per mile traveled. You...

Hello all,

I have the following generalised algebraic Riccati Equations of type:

A^TY + Y^TA + C^TC - Y^TBB^TY = 0;

E^TY - Y^TE = 0;

where A is 12x12 matrix, C is a 16x12 matrix, B is a 12x2 matrix.

However, the "CARE" function solves the different Riccati equation (http://www.maplesoft.com/support/help/Maple/view.aspx?path=LinearAlgebra/CARE)

Would you please...

Hello,

I have defined a function(say fun) to do certain task, it works well when I call it from a script file(say script1). However, when I copy the complete script1 and paste onto another script file(say script2), the function, fun, doesn't execute. It's very peculiar as my project requires lot of modification, so I copy the old script and...

If S= { <0,1>,<1,2>} and T={<1,1>,<2,3>} are ordered bases for R² and v=<1,5> and w=<5,4>, then can someone help me:

-find the coordinate vector of v and w with respect to the basis T by creating a procedure?

-I can make a procedure to find the transition matrix P_S<-T from T to S-basis, but can you help find the coordinate vector of v and w with respect to the basis S. Using P_S<-T?

Dear Mapleprimes,

I am trying to solve an Optimization problem analytically. I set up a lagrangian as follows:

L:= Objective function + mu_1 (constraint 1) + mu_2 (constraint 2)

I maximise with respect to two variables, call them x1 and x2

I want constraint one to bind but not constraint 2. Hence, I set mu_2=0. The I do:

diff(L,x1); diff(L,x2), diff(L,mu1), diff(L,mu2)

Hi,
I'm trying to import matlab function from m-file.

File looks like this:

    function out = xxx(omega)
    out = heaviside(omega);

It's only heaviside function.

And now, when I'm using "FromMFile" command in Maple it doesn't recognize Heaviside function. It imports that function as "heaviside" - witch small first character (in Maple we needs big "H").

Any help? 

thx 

Hello, I'm creating a rolling thin disk (rolling without slip) in the MapleSim, the model like the picture below (Fig. 1).

       ...

I need to make one "DensityPlot-point" (similar Statistics [DensityPlot] or histogram in 

Matrixplot) of a set of points (x, y). 

The set of points (x, y) was generated by the procedure.

Is there a way to generate it?

Thank you.
