i find that modulo is (Im(M)+Im(N))/Im(N) but where is Im command in maple?

after tried the following package, also not correct, i guess i should use quotient and Im command

with(MTM):
with(LinearAlgebra[Modular]):

Hom := proc(M, N)
Mdim := Size(M);
M_n := Mdim[1];
M_m := Mdim[2];
Ndim := Size(N);
N_n := Ndim[1];
N_m := Ndim[2];
F := kontraHom(M,N_n);
B := kohom(N,M_m);
C := kohom(N,M_n);
D := Mod(F, B);
E := Mod(D, C);

I am using the LinearAlgebra package. The function SinbularValues returns the singular value matrix S as a vector, i.e.,S*<1,1,1..1>.  Is there an easy way to recover S, itself, from this vector?

Hello,

In Maple 15 "Document" mode, how may I create a 2D fraction as *text* (as opposed to mathematical input that Maple evaluates)?

Thanks,

Hello,

My name is Jonas, and i'm trying to do some calculations on bending of a aluminium frame. Now i'm really confused why it wont plot! 

I attached my maple file. I hope my question is clear! 

Thanks in advance!

i find a link http://en.wikipedia.org/wiki/Exponential_integral

in the link, is Ei(x) = Ei(1,x)?

is Ei(1,x) called exponential integral?

what is Ei(2,x)?

what is definition of Ei(y,x)?

Point Groups typical to cubic crystals are Tetrahedral (Td) in Zinc-blende and Octahedral (Oh = i x Td) in Diamond.  Symmetry operations give rise to the widespread application of Group Theory most notably to generate basis functions which transform according to irreducible representations.  Much work has been accomplished using Single Group basis, compatible...

Hi,

i have two equations from these following type

Hey, any help would be much appreciated! For any 2x2 matrix A, I can use GaussJordan(A) and it will return its reduced form. But I want to write a short program that will return the elemtary matrices used during the process as well. Any idea how to do this?! Thanks!

I should need to solve the transcendental equation below in the unknown  theta0(k+1) , I am not 

able (Warning...). Is there any trick to solve it ? Why in this case Maple output is:

Warning, solutions may have been lost ????

 

solve(0.4254750000e-2*theta0(k+1)/DT^2+(-0.2500000000*sin(theta0(k+1))*lambda1(k+1)*

DT^2-0.4254750000e-2*theta0(k...

I need to install Maple 8 for the Mac OS. Would you let me know where to obtain it? Thank you very much!

Why the Maple, the power of zero to zero 1 and I do not indeterminate? thanks Zampiva Diego

For example, I have the expression:

f:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6)+5*ln(5*r)*Pi+5+x;

How to isolate terms in i and other terms (automatically) to get :

f1:=sin(i*Pi/2)+cos(i*Pi/4)+i+A[i]*cos(i*6);

f2:=5*ln(5*r)*Pi+5+x;

Thanks in advance

I think I will continue posting some good questions from
Fridays Killer Questions 7city Learning:

Question:

There was a hit-and-run incident involving a taxi in a city in which 85% of the taxis
are green and the remaining 15% are blue. There was a witness to the crime who
says that the hit-and-run taxi was blue. Unfortunately this witness is only correct
80%...

I am trying to take the inverse fourier transform of a dsolve/numeric in Maple 15 and I'm wondering if there is a way to do something similar to the fftshif in Matlab.

Here is the sheet so far, the fft's happen at the very bottom.  (any advice on the flow/syntax of the sheet is welcome too)
