Just wanted to let everyone know that there is a Maple 16 update available. Maple 16.01 includes improvements to the mathematics, interface, and plotting capabilities of Maple, including:

• Enhancements to the Physics package in the area of general relativity
• Translations of tutors and assistants into French and Brazilian Portuguese
• A correction to the problem in plotting multiple plots at once in non-Cartesian coordinates, as

Hi,

I'm currently having some issues while trying to find a way of getting the CPU usage inside Maple.

Is there any existing Maple function that will return the percetage of the CPU usage ?

Hello

I have Problem with the Maple command plotsetup, it does not seem to work within an if-statement.

What i would like to do is this:

1. Make a matrix with 0 or 1 as enteries

2. convert this matrix into a list where the 1's are points. (So the Matrix entery Matrix[1][1]:=1 would give the listvector:=[1,1]

3. plot these vectors as graphs and store them with the help of plotsetup

4. changing the matrix and rinse and repet 2,3,4 until satisfied

Dear Primers

I have an integral equation of the form below:

;

In this equation, u0,u1, s1, s2 are konwn constants and f(y) is a function with a certain exact form. I want to get the analytical solution

this error message hapened,but  i try process agin ,this erro disappeared, the proce is perfect, but  then it appear agin. is this a bug?  i use maple 16.

I'm working with some rather complicated sums involving absolute value, I'd like convert the sum into a piecewise defined function. For example

Attached are results I obtained in MAPLE 12.  Can anyone explain the contradiction?

In short, if I sum from n = 0 to some integer I get a FALSE when testing the equality, which is what I would EXPECT.  However, if I change the integer to a variable to represent that integer such as m--> the result is TRUE?

Note the change in the variable of beta to alpha inside the series expression within the parentheses.

Hi,

I have a problem with "subs" command in maple. When I use it the outcome does not show only the final result. It shows the (middle operations=final result).

For example, suppose that v(t)=x^2+1 is a function obtained from some calculations and L:=h*u(t). WhenI use: f:=subs(u(t)=v(t),L); it shows: h*u(t)=h*v(t)=h*(x^2+1). I want to show only the final results: h*(x^2+1). It make a problem in my next calculation in solving some differential equations.

Hello, I am new to maple and trying to teach myself as i go along. I am trying to plot a paramteric for a puck on a fristion less table that spins for differnt v_{o values. Here is my code: puckontable.mw}

I have valid Maple 15 licenses both on my laptop as well as on my desktop at work. Sometimes I would like to use the kernel of the desktop version (more powerful computer with more memory) with the worksheet-GUI of my laptop esp. since on Mac the X-window interface does not work. Since Maple has a client-server architecture (or kernel-frontend), is there a way---any way---to connect to the remote kernel from my laptop? I believe Mathematica has been able to do that for years.

Hi,

I am working with equations on Maple which depends on a parameter (epsilon), which can assume only the values +1 and -1 (I intent to replace this value only in the end of calculation). When, however, Maple computes the expressions, the result contains severals powers of epsilon, for instance epsilon^7 or epsilon^4. Since actually we have that epsilon^7=epsilon and epsilon^4=1, respectively, it would be very usefull to me if Maple 

Dear Maple Users

Let the density of electronic states be denoted

Suppose a Record is created as follows in Maple.

> r := Record( foo = [ ... ], bar = Record( ... ), ... );

If this is saved with save() command to a text file, a new line is automatically inserted at every fixed character length, and it is very hard to read. I want the Record to be stored to a text file in more human readable way. Is there any good way to do that easily?

hi

so ill preface this by saying my knowledge of DE equations is rusty at best and my knowledge of maple even worse so this may be a stupid question. im trying to model the dynamics of a system and when i solve for the DE equation it's giving me an accleration of zero (plotting a blank graph) when it definitely shouldnt be. ive attached the worksheet. DBM-variablemass_pro.mw

Hi, i'm trying to write the following, it works and is giving me the answer i want. But is there a way where i can write it in a simple manner? Please advice. Thanks.
