(1+x)^(m+1) > (1+x^m)* 2^m


here x > 1

I have attached a maple document with some questions.  Pleas answer in an attached document since my web browser of some reason cannot read maple-math in the forum.
By the way admin should take a look at the


What is the pattern in the following polynom: (how to generate them) 

1:     12 n^2 + 12 n + 1

2:    300 n^3 + 450 n^2 + 160 n + 5

3:   840 n^4+1680 n^3+1030 n^2+190 n+3

In the Belgium lottery they pick 6 numbers out of 42   (  there can't be 2 equals numbers being picked out )
Now for my maple homework , i must do some exercices in maple

1 ) Simulate the lottery
2 ) If you partici

I would like to declare spin states; spin up (alpha) and spin down (beta)

such that they form an orthogonal basis not necessarily using Dirac Ket notaion.  I am using the Physics package and Linear Algebra

When I try to use the Dirac Ket notation, I have noncommuting issues with the Cartesian basis

Cart := Vector[column](3, [Ket(X), Ket(Y), Ket(Z)]);

Spin := Vector[column](2, [Ket(alpha), Ket(beta)]);

<p>sys := [diff(v(s, n), n)+diff(u(s, n), s)+diff(xi(s, n), s)+A*n*(diff(c(s), s)) = 0, A1*(diff(xi(s, n), n))+diff(v(s, n), s)-c(s)+A2*v(s, n)+A3*c(s) = 0, diff(u(s, n), s)+2*A2*u(s, n) = A2*(xi(s, n)+A*n*c(s))-A1*(diff(xi(s, n), s))-A2*n*c(s)] The dependent variables are v,u and xi and the boundary conditions are: bc := {u(0, n) = 0, v(s, -1) = 0, v(s, 1)} other things: -1<=n<=1. I tried ans := pdsolve(sys, bc, xi(s, n), u(s, n), v(s, n)) i also tried ans := pdsolve(sys, bc) I keep getting error messages about the dependent variables.

According to my experience so far, maple is stupid in image processing.

Frustrated with its functions.

For example, in plotting functions, only bmp, gif, jpeg is supported

while in image package, only jpeg, tif and bmp are supported.

So we take the intersection, only bmp and jpeg files can be used if i want to use plot and image packages at the same time.

If i want to do image processing on the file generated from the plot, like transparency stuff, it is not achievable!

And it totally doesnot support opacity!!


hi all! i am **brand new** with maple 13 as well as trigonometry, which i am using the program for. i have figured out how to plot the unit circle with the command:

>plot( [cos(t), sin(t), t=0..2*Pi] );<

I would like to experiment with the Mastery Dialog option e.g. making a tutorial. Does anyone tried this in practice? And can I download a question bank that uses this option?


kind regards,

I am uing cmaple.ext to generate batch of images.

However, i found some of the functions are not the same as i execute from the worksheet from standard maple interface.


There are lot of white space around the image...

Is there any way to reduce them?

Good Morning,

Would anybody be kind to help me with the attached Maple worksheet. My goal is to use Maple procedure to generate all the equations and then solve the equations for all the variables. Also, I have attached the PDF file on the paper I'm trying to develope, the equations are on page 8. Please Help.



For solving a 2nd order hyperbolic PDE numerically (pdsolve/numeric), is it possible to choose more restricted and different time/space ranges, rather than what is defined in initial/boundary conditions? (assuming the fact that one defined Cauchy initial conditions for time variable at t[0], and Dirichlet boundary condition for space variable) thanks
I have a collection of polygons in 3D that are in various colours. Some of these polygons overlap. How do I control what colour the overlapping portions are? The overlapping part may take the colour of one of the polygons. Thank you.

dear i have very complex problem may it wil easy for somone, i have 36 equations in maple that i have to use in matlab to simulate and the equations have to take som numercal values in matlab, and it has to generate some numerical values while running in a loop. i have used the with code generation option in maple. and it produce a code for matlab.
