can i distrubute some random particle with an arbitrarity function in maple, for example p(r,theta,phi)=p0*sin(theta)/r, 0.01<r<1, 0< theta<pi, 0<phi< 2*pi. For such distribution we expect many particle in equator.

many thanks

After a few steps and derived out a formula include a hypergeometric expression

hypergeom(....)

in this hypergeometric expression, there are more than two parameters in maple for example

hypergeom(X,Y,Z...)

from some paper said G(z*q; q^f)

i am not familiar with hypergeometric series

how to substitute z*q and q^f into a formula include a hypergeometric expression.

i am unable to solve the following inequalities:

ineq1 := (4-(3/2)*q+(1/2)*sqrt(28-24*q+5*q^2))*(1/2-(1/2)*q)

ineq2:=(3-q+(1/4)*sqrt(84-58*q+10*q^2)+(1/4)*sqrt((4-2*q)*(3-q)))*(1/2-(1/2)*q):

solve(ineq1<1,q)

solve(ineq2<1,q)

"Warning, solutions may have been lost"

please help me here

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]

When I solve a system of equations, the result, even if it's a single numerical solution, is no longer given as a number, but like this:

Now i'd like to use the variable a with the value

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...

Hello,

recently I was helped on this forum when I asked how to work with exterior products:

http://www.mapleprimes.com/questions/137431-Efficient-Way-To-Work-Out-Exterior-Products

Now I would like to know how I can efficiently let Maple solve systems of equations between wedge products.

For instance, I would ask Maple to solve

Hi there!

I'm trying to decompose a measured force (with Force and Moment block) to visualize the three components XYZ independently, using the Force Arrow block. I tried using demultiplexers but an error occur:

connection element mismatch: connect((Main.M3_1.y[1], Main.M3_1.y[2], Main.M3_1.y[3]), /*struct*/ (Main.DFPSubsys1inst.force.r_0, /*struct*/ (Main.DFPSubsys1inst.force.R.T, Main.DFPSubsys1inst.force.R.w), Main.DFPSubsys1inst.force.f,...

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:
