I've tried to install maple 10 in windows vista but it seems imposible the setup keeps saying this.."please wait, maple 10 is being configured for your system, this make take a moment..." i've left my computer on all night but the installation doesn't end...any ideas on how to solve this problem? thank you.

Could you please explain the following:


1) str1 and str2 should be global variables right? I mean so we can call them
after the Create statements....

2) When I execute the below code and then call str1 and str2 I dont get any html output.
The " " are empty.....why?

X1 := proc () local str, sid, b;  global str1;

My question is similar to the one referenced, but a bit more complicated.

Considering a PDE of order n, I would like it to be collected by the order of differentiation.

A simple example:

simplify(( (3+4*x)*diff(f(x), `$`(x, 2)))+(5+4*y+z)*(diff(f(x), x))+(1+r+y)*f(x))

where the idea is to return to the form prior to simplification, including the sort by differentiation order.

After it is simplified, I can get the coeff of only the highest order derivative, as

What's wrong?
I need to minimize (z-Z) ^T.E^-1. (z-Z).
How can you see in the first Call to LSSolve worked. By introducing objectivejacobian I have problems

Recently, I submitted for publication to a peer-reviewed math journal

a formula for the n-th order implicit derivative given an implicit function G(z,w)=0.

i.e. dz/dw = - Gw/Gz where Gw and Gz are partial derivatives of G with respect to w and z, respectively. Anyway, I proved the general formula for d^n z/ dw^n.   I have since proved the generalization of this to implicit functions of several variables, G(z,w1,w2,...,w(N))=0. A good mathematician...

PDE:  u_tt=c²u_xx+f(x,t)   ; f(x,t)=a*sin(2*pi*t/P)

BC: u(0,t)=0,u(L,t)=0;

IC: u(x,0)=0,u_t(x,0)=0;

who can show me the steps by using maple? and i need help to plot the graph as well. thx!

Is there a function in Maple which allows to send emails?
I am bulding a maplet where I want maple to send a email
as a reminder at the end of each month to a specified emailadress

Is this possible ?

Hi,

imagine I have the following line:

(y/2)*(4/3)*sin(x);

can I tell Maple not to merge everything together? I want to have it all seperated, like a separate fraction for y/2 another for 4/3 and then comes the sine, with small spaces between them, indicating multiplication.

thanks.

I would also like to have an answer to that question !
How would I specify the below code (yahoo finance) for google finance?

If I type FormatTime() then I get todays year,month and day.

What should I type if I want the year, month and day one month ago?

I am just moving from Mathematica to Maple, since I just found out Maple is better suited to my needs. I checked some basic functions, and Maple seems to be pretty perfect. However, I cannot find a way to do a revolution plot. In Mathematica I usually used the command RevolutionPlot3D. But here, in Maple, I cannot find a way to do it. Can someone help?

Here is a sample of what I am talking about:

I can`t solve this equation

Dear all,

could you please guide me how to find my post quickly on this site? Can I save it somewhere to access it quickly when signing this site again?
