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)?

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!

Hi,

I need some help, I have tried some variants of finding of min of an array but it did not work.

I have declared an array (T:=array(1..10), then using a cycle to calculate the values of this array. I can read this array and plot the data and see the min and max values(for example: (1,2,0,3,4,5,6,3 ,-1,5)), but I can not automatically calculate  the min and to find that this is exactly T[9].

Is there special function that I can use for this or...

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 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

I understand that porting Maple to Android would be a pretty big job, but does anyone know of any plans to at least make an Android program capable of viewing Maple worksheets?  It would be really handy to be able to show my work to someone using an Android tablet, which is certainly capable of rendering graphs and such.
