I'm not sure if u have seen this website 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...

Hi all,

Here is the problem, I will try my best to describe it:


Firstly of all,




In this system, the 'j' is a time varying parameter, and the...


I was trying to find the generalized eigenvalues for the (3x3) matrix pair (P,G) defined below. (I have left everything in symbols with beta and kappa both of which are strictly positive real numbers). For some reason the command Eigenvalues(P,G) is only returning 2 generalized eigenvalues. Any ideas why it doesn't return 3?




Anyone knows how to use an expression like t^n, where t is a polynomial variable and n is an intager variable, in such a way that (t^n)/(t^m)=t^{n-m}? Actually, I would like to use it inside some package like polynomial tools, in order to normalize such expressions.


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

I want to graph the portion of the plane 2x + 3y + z = 6 that are located in the first octant of a xyz coordinate system. The following implicitplot3d should in principle do it:

I have a collection of functions defined either in terms of a single variable - call it r - or in terms of (r and) the other functions of r.

To be more specific, there are two free functions B(r) and N(r), a function theta defined in terms of N(r) and B(r) (and their derivatives) and r, and a free function V(theta).

Finally I have a function, call it f, written in terms of B(r) and N(r) (and their derivatives), r, and V(theta) and its derivatives with respect to both theta and r.

What are all the maths that are on this program?

Hello Maple experts,

 I want to find out k-th probability (denoted by c(k)) which is expressed as an integration of summation for values ranging from j=0 to k. The function is very complicated , I have attached the PDF for expressing the mathematical term properly.

I am able to find out the c(k) for a given value of k, if k is specified in the beginning of the maple program. But I am unable to make it generic form of k.

I have also attached the...

On a calculus 2 test I was given to review the students were asked to find the derivative of arccosh(x)*sqrt(1-x^2).  Maple gives the answer -arccosh(x)*x/sqrt(1-x^2)+sqrt(1-x^2)/(sqrt(x-1)*sqrt(x+1)).   This is the same answer, in a slightly...

Maplesoft has these interesting bits of Math on their website.  For example this one here

It is all nice and all but I would like to see some reference examples to maple for each one, a cool application worksheet that portrays each one nicely. 

Using the example link above I searched maplesoft application center for navier stokes...

Dear All:

 I have a curve about mosfet  Coss Vs. Vds . the detail math relationship can be found in the following picture: 


 Can anyone fitting this picture by simple math function.

 PS: pls don't considering piecewise function 



I wish to enter in the math dot operator but I can't find the way to enter it in the document mod. I also searched the help and did not find a way.


all I want is to enter dot(varphi)




I'm creating a table of random math problems for my daughter to print out.  How do I get more columns?

a := rand(1 .. 15):
b := ["+", "-", "x", "/"]:

for i to 15 do
end do;


Hi all, I found that the expression:


automatically simplifies to


Is there a function that will return


which is one fraction, instead?
