Hi,

I was reading the manual for Maple 13 and playing with some commands.

There is an equation: sin(x)=cos(x) and you can solve it by the solve command.

If you want all solutions, you just put there AllSolutions attribute and you get

(1/4)*Pi+Pi*_Z1~

I wonder why there is a tilde (~) behind "_Z1", because each integer satisfies

the equation (there is no need for an assumption).

Given the initial shape of the longitudinal axis of a curved bar is given by
y₀(x) = a*sin(Pi*x/L)

where a is a constant and L is the length of the bar

and proceeding to calculate the deflections due to deformation from the diff. eq.

EI (dy₁/dx) = -P(y₀+y₁)

the ode for deflections is obtained

dy₁/dx + k*y₁ = -k*a* sin(Pi*x/L)

where k is a constant = sqrt (P/EI)

Can anyone known of or recommend a program fro converting Mathematica notebooks or files etc., into Maple worksheets

Hi, Can anybody explain why Maple is crashing? Does it happen with Maple 13? > c:=alpha->solve(-alpha*(alpha+1)+x^(2/alpha),x); # I am too lazy to solve the eq by hand. > c(a); # Maple returns the correct value although that is difficult to see from the text version of the output /1 / 2 \ \ exp|- ln\a + a/ a| \2 / > c(1.5); # This always crashes Maple 12 on my Mac OS 10.5. Maple announces tha the connection to the kernel has been lost and I must restart. thanks,

If I have autosave on and I'm working on a worksheet and then if I change the name of the directory in the middle of my worksheet.  Autosave re-generates the old file name and saves it there.  Not really a major bug - not many people change the names of their directories in the middle of working on a worksheet anyways.  Never-the-less I managed to stumble across it. 

Try following,

Factor(a^4 + a^2*b^2 + b^4 + a^2*b*c + a*b^2*c + a^2*c^2 + a*b*c^2 + 
    b^2*c^2 + c^4) mod 2;

I couldn't get an answer in a reasonable time and interrupted calculations.

Hello,

I am maintaining a C++ application that requires Maple code generation features to produce C code.

This application uses the EvalMapleStatement (kv, statement) function, where 'statement' is actually a CodeGeneration[C](...); command.

The application has worked correctly before, and the generated code has been incorporated as modules into other applications that make use of it.

Hi,

In which language the combinat package is written ? In C/C++ or in the Maple programming language ? When I call a combinat package function, from which file comes the function code ? I suppose the code is in a binary format, isn't it ? Thanks.

Is this board the best place to ask about issues with Maple V Release 5?

I'm trying to learn about animated 2d plots by using examples in the bundled help file, but something is wrong.

Here's one example that I tried:

restart ;

with(plots) ;

animate( sin(x*t), x = -10..10, t = 1..2, frames = 50) ;

Maple renders only what appears to be sin(x) from x = -10 to 10, with "jagged" local minimums and maximums.  If I simply plot sin(x), then the graph has smooth curves.

There is no animation.

It appears when extended mode is selected, the Round screen display to ... under precision it is still not working. 

When using the with(ScientificConstants) package and calling on the elements for it's properties some elements do not append the programming code. 

GetElement(1);  contains proc and endproc's and so does GetElement(2);

Element 3 - 5 don't but 6 - 10 do, and 11 - 16 don't and 17 - 18 do, 19 - 32 don't and 33 -  well you can find out yourselves.  Point is it's not consistent and needs to be fixed. 

please help me...as you read the subject of my   message you easy t think an idea what may you have..email me willing t help...

coz we are developing another sorting algorithm that claims that our algorithm is faater than quick sort algorithm in terms in numbers and characters..

please help  me to evaluate our new develop algorithm..

I want to report some progress in finding a closed-form for the MRB constant.

I found a sequence of closed-forms involving the MRB that gives "0." with interesting accuracy far beyond machine precision. To see it for yourself, simply plot 1 + Sin[Pi*(5060936308 + 78389363*Floor[n])/m],
where m is the MRB Constant, for n in any given domain. It is
