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?

I'm a new user with Maple. Please give me a clue about this, i tried search over HELP but i cannot find anything. My first question is: how can i get just a real solutions when i solve for an equation ( this one got 2 complex solutions ). The 2nd is about the linear system, I got ROOTOF solution, i think it came from the complex solution. Please download my maple file to take a look. Thank you.

Hallo everybody,

I am using maple 8 to numerically evaluate the roots of a 1d polynomial in a given interval. Does anyone know how to force fsolve to compute all the roots  in a given interval  and  not just a single one. Alternatively, does anyone know if it is possible to specify an interval to compute the roots with the solve command? Thank you in advance.

A Maple user in Ireland asks:

Basically when we call BooleanSimplify using the openMaple API, with very long expressions, after a significant period of time maple calls the textCallBack with the tag MAPLE_TEXT_QUIT and nothing in the string passed to the same function. Could you shed some light on what maple_text_quit is and why maple might be returning this. i.e. could it be that it has hit some internal limit, or that It is hitting some external limit. i.e. malloc
