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)

Hello everyone

It seems I can't live without keyboard shortcuts :-) Is there is a short cut for the following commands:

execute the entire worksheet
remove output from sheet
join/split execution groups

I'm on mac.

thanks.

hi

i have the following function

f[1](x):=_C2 (e)^x-_C1 (e)^(-x)+1/2 x (e)^(-x) h1+1/2 (e)^(-x) h1+_C3

with thease boundary conditions:   f[1](x))=0,diff(f[1](x),x))=1,diff(f[1](x),x),x=infinity)

i want to find cinstants C1,C2,C3 where h1 is arbitrary parametr.

i write the following code but its doesnt work correctly

s1:=simplify(subs(x=0,f[1](x))=0);
s2:=simplify(subs(x=0,diff(f[1](x),x))=1);

I am calculating the dotproduct in maple 15 of two very large vectors. Are there any tricks/ways to speed up such a calculation? Maple is taking a very long time to execute the calculation and I am unsure whether it will actually return a result.

I'm using maple code of the form DotProduct(vector1,vector2);

Any advice ?

On the usenet newsgroup sci.math.symbolic Prof. Richard Fateman posted a question (or here) recently about what mechanisms a math application could use to handle the situation of negligible imaginary parts of computed data when plotting.

An example could...

Good Morning.

I would like to know where Maple is statistics compared with other software. As a justification for the thesis i am doing. I found a page http://www.scientificweb.com/ncrunch/, but a report in 2008. I wish something more recent.

Thanks
