MaplePrimes Questions

My problem is that Maple does not give answer at all for the initial value problem, so I need a help. If does exist a solution how can I obtain it?

Thanks in advance,  Sandor

What is the (symbolic) equivalent in Maple for

   [ V  D ] = eig( A, B, 'chol' )

for given matrices A, B ?

Hi!

I was trying to install Maple11 on my computer (Windows Vista Home Premium, 2GB on RAM) but I cannot do it, when I executed maple11windowsinstaler.exe appear this message:  "Installer user inferface mode not suported": Unable to load and to prepare the installer in GUI mode... Why appear?? I need to intall maple as quick as possible. I tried to run the installer with  "run as administrator", but i cannot install.

Please, help me!!!! =(

Hi, I am just courious and I want to delay the output like: If I ask maple to do an integration, first it displays the question: Int(x,x); then after some time it displays the answer int(x,x); is there a way to do that?

I'm a teacher and I'm teaching my students about graphing trig functions. Well, they do not know about radians yet and I need to keep everything in degrees and would like to plot my graphs in degrees and show that the graph is in degrees on the axis, but I can't find a way to do this. Can anyone help me with this!

thanks,

Hi,

I am trying to convert tan(z) to sum form using the convert(...,Sum) command and using some information from FunctionAdvisor.
The second operand of FunctionAdvisor( sum_form, tan) gives me the domain of validity.
I would like to use this info during the conversion as assumption, but it doesn't work for me.
(Of course, the first operand is the required sum form, I am just playing with maple).
Here is my problem:

Unfortunately piecewise() is a builtin so I can't see the library code.

I'm trying to construct a sequence of arguments to piecewise() programmatically, and to assign the result to a function but I just can't seem to set it up correctly.

I have a 10x18 matrix, each row of which will be used to define a piecewise linear function, so the columns in a row define the endpoint values of each line segment.

Essentially what I'm trying to do is the following (giving some Maple pseudo-code which doesn't work, but hopefully will get the idea across):

On page 99 of Dr. Euler's Fabulous Formula, Nahin says that:

int(int(`f`(s), s = 0 .. t), t = 0 .. x) = int(`f`(s)*(x-s), s = 0 .. x)

is true and I believe it, but I can't get Maple to confirm it.  How can I get Maple to agree with Nahin?  Are there assumptions that will make it happen?

 

Hi,

I want to evalute in degrees.

 

restart:with(Units[Natural]):

sin(45 * deg);  # it works

 

>alpha[1]:=4.25 * deg;
> theta[1]:=11.31 *deg;
> theta[2]:=78.69 *deg;
> alpha[2]:=-9.25 *deg;
> a:=1400.00;  #  a and b should be real values
> b:=509.90;

>-b*sin(alpha[2]+alpha[1]-beta[1]-theta[2])+b*sin(beta[1]-theta[2]):

Error, (in Units:-Standard:-+) the units `arcdeg` and `1` have incompatible dimensions

not working...

How to input the character underline('_') in Maple,for example,typing variable name "cs_e"?

The code generates lines parallel to the opposite side of a given triangle. How can I control the animation to stop at x=10 or not to go outside the triangle.

Dear All,

I've just started using MapleTA and I'm exploring the Latex capabilities. The test question that I have constructed looks like:

\begin{question}{blanks}
\qutext{Test  \blank[formula]{\var{ans}} Test.}
\code{
$a2=Matrix([[1,2],[3,4]]);
$c=LinearAlgebra[MatrixInverse]($a2);
$a=rand(5,9,2);
$inc=int(rint(3)+2);
$b=$a-$inc;
$ans=int(10^$inc);
}
\end{question}
\end{topic}
 

However, I get the following error during latex conversion:

What practical limits are there to the size of a system of simultaneous nonlinear equations that fsolve() can solve?
