So I am fairly new to maple and haven't really worked with it up until a couple of weeks ago. I am taking a physics course which requires us to do some work in maple and I am struggling to learn some of the concepts behind the data structures.

I have to essentially be able to parse a list of "Student Records" with names and marks received, and then store the data in a new list with the student name, and their average.

Essentially I am given:

[code]

Revision Note:
I have updated the graph in the attached Maple document based on Doug Meade's comment below.

Does any one has any idea about "Ndynamics" package?

Whenever, I try to call it, maple gives this error

restart:

with(Ndynamics);

"Error, invalid input: with expects its 1st argument, pname, to be of type {`module`, package},

but received Ndynamics"

Is this an old package and replaced by a new one?

Thanks

Hi,

     I wish to plot the trajectory of a ball, and I set up my three differential equations and solved them numerically. I can graph the x, y, z components but I can’t figure out how to plot 3D space curve of this (and animate it if possible).

I used dsolve, numeric rtk45, so the output is [t, x, x’, y, y’, z, z’] so I tried to assign the second (and 4^rth and 6^h) term in the list to a function

I find I have a number of strange and unrelated errors.  I am new to Maple, but have been using Mathcad so am somewhat familiar with these systems. 

One of the problems I have has to do with confusion between literal and standard subscripts.  I find it difficult to get Maple to recognize literal subscripts using any of the recommended methods.  When I do get it to work, and I'm not sure what I'm doing wrong, when I paste pieces of...

hi, 

I am a newcomer user(maple16) and am trying to make a graph of energy * time forced oscillation
but I'm having this problem

Consider the differential equation 
                   d                          
                  --- y(x) = 2 y(x) (y(x) - 4)
                   dx                         
 on the rectangle  -1 < x < 1, -2 < y < 7.40 in the xy-plane.

 (a)  Use DEplot to plot the direction field for the differential equation on the given domain.  Assign your answer to my_plot_1.

I'm trying to create a matrix that mimcs the FFT equation as seen here. (Note that I don't want to do the transform, I just want the symbolic matrix of it.) I want to make the matrix in terms of the symbol omega, but I also want it to reduce correctly. Here's what I mean:

I used this post to figure out:

Write a function to compute the n-th partial sum of the alternating series
            
1-1/(4)+1/(9)-1/(16)+...+(-1)^(n-1)*1/(n^(2))

Specifically, the procedure takes n as input, and returns the sum of the first n terms. 

Can someone help me with this? I'm not very good at using procedures.

Find the positive integer  m that satisfies the equality below : 10P4=m!

Calculate the determinant of the square Vandermonde matrix     (A is alpha)

Heey

I have a problem when I call the Eigenvectors i get:

>Eigenvectors(Transpose(K).K);

i get the answer i want but every time i execute the worksheet my eigenvalues swich places aswell as the eigenvector.

Someone that can help me how i can sort or something like that to freeze the eigenvector output? so i can use some of the output to caluculate furhtere on and when i execute the worksheet i know that me eigenvectors and eigenvalues...

Regards, I have a question about the solve function in maple

How does the solve function works?

I know if you have a random eq lets say y:= x-> x^2 + 5 x

and I use the function like....   solve(x^2+5x = 8) it will solve it for me giving me numerical values for x or the roots of x

If I have an eq w(x) and it has constants lets say w:= x -> a[1]x^2+a[2]x^4

and i solve this equation in this manner:    solve([w(0),w(1),D(w)(0),D(w)(1)])

 Write a function to compute the n-th partial sum of the alternating series
            
        "1-1/(4)+1/(9)-1/(16)+...+(-1)^(n-1) * 1/(n^(2))"
         Specifically, the procedure takes n as input, and returns the sum of the first n terms. 

So I am kind of lost- I've tried 5 different procs but keep getting more confused. Here is current one:

prob := proc (N) 

local a, u, n, q; 

 G := proc (N)

 local s, n;

 s := 0.;

 n := 0;

 while n < N do 

n := n+1;

 s := s+1/n

 end do;

 [s, n] 

end proc;

             G := proc (N) local s, n; s := 0.; n := 0; while n < N do n := n+1; s := s+1/n end do; [s, n] end proc
Compute  G(1.0),G(2.0), .....G(7.0)   try to figure out what the procedure G is doing

> G(1.0);
