HI,

I am struggling with simple multiplication shown in the attached file:

Is there any specific multiplication command I should use. 

Pls guide me in respect of how to make plot after multiplying A and B

Thanks in advance

Good afternoon

i have problem when i am using components.

i want to solve a determinant equation and show in MathContainer4

thank you for your help

Is it possible in Maple to choose the dimensions for a plot? I mean to choose the height and the width of the plot?
For example, to enlarge the plot to the whole width of the maple page? Is it possible?
I need to do this because I have to plot together objects of different dimensions and so the smaller ones look too small, so I would like to enlarge the plot to solve the problem. 

i calculate a polynomial as following

yn := f(x) = _C1*hypergeom([-(1/2)*n, 3/2+(1/2)*n], [1/2], x^2)+_C2*hypergeom([2+(1/2)*n, 1/2-(1/2)*n], [3/2], x^2)*x

want to get the polynomial with degree n  for  summation_n_from_0_to_infinity y_n*z^n/n!

such as n = 1 n = 0 n = 3, but above yn is hypergeom, is n represent degree, if so, i use subs, then is finished, if not, how to get polynomial with degree n?

What is the distance between the trigonometrical polynomials of the form a0/2+a1*cos(Pi*x)+b1*sin(Pi*x) and the polynomials of  degree at most 1, ie c0+c1*x, in the Chebyshev metrics on the interval [-1,1] and in the L^2 metrics on the same interval?

I have a set of nonlinear and coupled PDEs for a cable actuated system. I want to transfer this set to a set of ODEs and write it down in Matrix form. I used Galerkin's method and derived the ODEs in discritized form. I have a problem in converting this set of equation into a matrix form like "Mq"+Cq'+Kq=F". The derived equations are very complicated and contains some nonlinear terms. One of the three equations looks like this:

I have been investigating Predator-Prey spatial models, e.g.

I have a problem.

I solved a problem, but i like to get one solution for one variable.

i send my project.

help me please.21-07-2011_-ecuacion.mw

Hi Dr. Kamel Boughrara,

I have a question,  I know phi = B*A, but in code i can't understand a part of it, can you kindly explain it in engineering terms.  

kindly see the attach file for phi.

Second question

why e-->sum(factor(e(t)),n=1..100), wht this means, 

Hi guys,

I am working on the following pde

m₀=-Bw_ssss+(F_t-Bw_ss²)_s(w_s+r_s⁰)+(F_t-Bw_ss²)w_ss+q

where

F_t=EAe+T₀+p_wgPiD_o² (H_w-z)/4-p_mgPiD_i² (H_m-z)/4

Hi Dr. Kamel Boughrara,

I have question regrding the analytical solution in section 3.3,  I am attaching a file.   Question is regarding  the programming you did, does it has any effect on the solution.  Because i tried to change the values for p, and other variables but could't see the effect.

Also wht the following variable means;

Hi i´m writing a paper about math and i use maple 10 and M. Word 2007 for it, i started with a Laptop with Windows 7 and when i finished it, i open the archive in a desk computer having the same especifications  i notice that the images of ecuations were altered changing "+" and "-" for "C´s" and "K´s", i tried a lot of computers with others especifications and my problem still the same, i changed the format and other stuff but i can´t...

i use symmetric function package

with(SF):

i would like to know after calculating the basis toS(....)

which function can be used to convert into polynomials?

as i expect to get the sequence from any polynomials generated from it

Hi:

I am running a home network, XP and Maple 11 on the old computer, Win 7 and single-user Maple 15 on the new.

It took a long time, but I finally got a wireless network running, so that Win7 on the new computer can open and access all the files on the old computer.

But when I run Maple15 on the new computer and try to open an old computer file, Maple 15 cannot see the old computer or any of its directories, even though it has a "network" tab on the "open" command.
