A new edition of Maplets for Calculus  (M4C) is now available.  M4C v1.3 is a collection of 129 maplets for calculus students and instructors.  The 35 new maplets fill in some gaps in the coverage of precalculus and single variable calculus and begin to address multivariate topics. Each maplet provides a customized graphical user interface (using 2D and 3D graphics and animation) to provide immediate, step-by-step guidance through an endless supply of random ...

Hi,

In "Maplet Builder", how can i define a  procedure?

(Thank you  for your attention.)

Hi there,

i've wirtten a library for maple12, say "MyLib", which is given by the files "MyLib.ind" and "MyLib.lib".

I've done this via

> restart;  
>  march('create', "<path>/MyLib.lib", 1);
>
> read "functions.txt";
>      
> savelibname:="<path>";
> savelib( `MyLib` );

where "functions.txt" is given as

MyLib:= module()
 

How would I compute the x-coordinate of the symmetry axe of a quadratic function?

How could I write this as a procedure?

Thanks alot in advance.

How do I convert an expression like 22=K/.9 to latex.

If I right click 22=K/.9 or write latex(22=K/.9) I get  22= 1.111111111\,K - in other words it decided to evaluate 1/.9 before converting it.  To me this 1.11111 is wrong - it's an ugly approximation of 1/.9 - why can't it just leave the equation alone?

So again, is there a way to convert an expression to latex without this evaluation happening? 

(I'm using maple13)

Thanks,

I'm in a calculus course in college right now and my professor wanted us to buy a copy of Maple, so I did.  I bought it for my Mac, but the software seems to be having trouble with basic operations, like adding, subtracting and multiplying.  If I were to try and add 2+3, for example, I can type in "2," but then when I try to type in "+," it deletes the two instead and freezes the Maple program itself.  I have no idea what's going on.  PLEASE HELP!!!

How to solve with numeric pdsolve?

first domain: from 0 to x1 (for example: from 0 to 0.2), thermal diffusivity, a1=1*10^(-6), lambda1=3
second domain: from x1 to x2 (for example: from 0.2 to 0.3), thermal diffusivity, a2=5*10^(-7),lambda2=1
IC:=T(x,0)=298 for both domain,
BC1:=T(0,t)=1200;
BC2:=T(x1+x2,t)=D[1](T)(x1+x2,t)=-10*(T(x1+x2), t)-298)/lambda2),

Hi,

I have this procedure:

f := proc(x) if x < 0 then x^2+1; else cos(x); end if; end proc:

When I calculate NLPSolve(f,-Pi..2*Pi); the result is good. In NLPSolve, f(Pi) or f(-Pi) are also calculated.

When I want to determine f(Pi), I have this error code:

Error, (in f) cannot determine if this expression is true or false: Pi < 0

Why ? 

I must change my procedure with adding "evalf" to get a result for f(Pi):...

Suppose I have, say three arrays. I want to perform division on all the same positional elements of the array one and two, and raise the result to a power of designated by the same positional element of the third array.  In other words, the function applies to each of the elements of the array separately.  How do I do that without getting into programming?  Ratch

I would like to pay the attention of the MaplePrimes users
to a Robert Chero application.
This is a Maple package on graphics, which can be implemented in Maple as a usual package.
It  has community rating 4.5 stars. This package can be downloaded from http://www.maplesoft.com/applications/view.aspx?SID=1671.
It was submitted in 2005 when MaplePrimes started. Because of this reason this...

I've written a procedure which currently outputs, for example, 3/8*2^(1/3)*k^(4/3). However when I plot this it doesn't give me the correct graph that I'm looking for. I've found that rewriting the equation as  3/8*2^(1/3)*(k^2)^2/3 will give me the proper function in Maple, however I don't know how to get my procedure to output the equation in terms of k^2. I'm sure there's a fairly straightforward solution- does anyone know what I'm missing?

Cheers.

I'm taking a calculus of variations class and checking some answers with Maples VariationalCalculus package and the EulerLagrange command in particular.

I've done an exercise by hand for which I don't get the same results from Maple and I'm trying to see why.

Can anyone help me construct the EL equation "manually", in partcular how do I get the partial derivartive of an expression containing x, y(x) and diff(y(x),x) with respect to diff(y(x),x) ? That...

Has anyone successfully integrated a 3D plot from Maple (X3D?) into PowerPoint that can be manipulated within a presentation?  I have read an article on Tecplot's (another graphics software package) web site that explains how to export a Tecplot file as an X3D file and then embedding the X3D file into PowerPoint using a X3D plug-in.  See below:

Hi,

I'm using Maple versions 9.5 and 14.

I have a quite complicated functtion defined by means of a piecewise statement. Translation of that function into C code is required, so I tried to use CodeGeneration[C] and codegen[prep2trans]. The help of Maple version 9.5 tells me that the prep2trans command isneccessary to get the job done. It's about converting the MAPLE piecewise instruction into a  if ... then ... else if ......
