hi,

i have an exercise ,i have to do for sunday:

a program on maple 13 of o numerical solution of heat equation for  semi-infinite rod where a finite quantity of heat is injected into the left end in the form of pulse instant

please i need your help.

I know

convert(sin(x),expln)

can convert sin(x) to expression which has "exp"

but how to produce the inverse operation?

Maple people:

I just installed Maple 16 on my home PC.  I prefer using Classic Worksheet Maple, so that I can actually tell what I have typed, and what I type appears in red typewriter font.  I also would like matching parentheses to blink when I enter stuff so I enter the right number of parentheses.  Maple works this way on my office PC, but I can't get it to work this way at home.  I could simply use regular Maple 16 (not Classic Worksheet...

Dear all,

need to take data(a,u) from eq1 and plug it in eq2

eq1 is:

eq2 is:

Then need to plot data (a,v)

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

I did that:

points:=seq([a,evalf(solve((alpha+(l+alpha)*u+alpha*k*u^2)*a=u*(alpha+(l+alpha)*u+alpha*k*u^2...

In Maple 17, the Student MultivariateCalculus package has been augmented with fifteen new commands relevant for defining and manipulating lines and planes. There already exists a functionality for this in the geom3d package whose structures differ from those in the new Student packages. Students...

Hi,

I'm trying to write a function in an 'n' dimensional vector such that I can call upon this function in a loop to define hessian matrices, or simply evaluate the function value for a given input. Here's an example:

F(x,y,z)= 6*x^2 + 3x*y^2 - 1.5*z^3

which is a function in 3 dimensions with x,y,z representing the 3 components of a design vector.

I want to be able to call upon this function in a loop such as:

I was given the following MGF and need some help determining the E(X), Var(X) and P(4.1<X<4.7) using Maple

MGF of X is M(t) = 1/(1-3t) , t<1/3

How can I get Maple to do this for me?

Thanks again :)

Is there a possibility translate Maple code to Reduce code ?

Hello,

do 3D-OpenGL-Graphics in Maple 16/17 on Linux-x86_64 (openSUSE 12.2/12.3)  work with Intel HD 3000/4000 Graphics?

Thank you very much.

Maple 16 is crashing when saving. I have this problem in both

my desktop and laptop (PC, Win7), classic and standard worksheets.

I noticed that short files present no problem, but whenever the

worsheets are, say, more than 5 screens length, Maple 16

crashes when saving.

Anyone with the same problem? Any solutions? Thanks

I mean not open these files, and ctrl+A select whole file and copy to one file.

How does one solve integral equations in Maple?

Is there any way to convert the output of ToInert to a graph/tree representation?
ToInert's output type is a function and I've tried converting it to an expression  first but didn’t succeed. I've also looked for functions in the GraphTheory package that could help in this process but didn’t manage to find anything useful.
Thank you.

Attached is my sheet. Please have a look.  my_scrach_Sheet.mw

Have a look at the last command of the sheet.

I am trying to extract integrals from the equaions(eq10_1, for example) using 'op', but it isn't working as expected, is it a bug or I am doing something wrong?

Second question: 

I am not been able to do sorting for all these equations, any suggestions?
