Dear maple team.

I would like to suggest something about the treatment that Maple makes of arithmetic modulo 2.
If you write the command:"x+x mod 2", the Maple output is "0", because "x+x" is always even. Perfect.
The problem I have is:
When  you write "x^2 + x mod 2", the Maple output is "x^2 + x"  instead of "0". Maple doesn't takes into account when simplifying that all the variables are idempotent modulo 2 (i.e, x*x = x)

If I write

Can maple use a Differential Operator somehow in the following sense?

Instead of expanding (D-p)^n where p is a constant and D the differential operator and n an integer and then in each term writing D^n(f) for some function can I just leave the expression as it is like

(D-p)^n and acting on everything on the right?

I have this sequence:

How can I put  this in maple, assess if it converges or not and if it is possible, calculate the limit to infinity.

 

Thanks

Warning, solving for expressions other than names or functions is not recommended.

is the warning I get every time I try to solve for solve(ode1 = ode2, theta/T)

Is there any way I can solve for an expression (i.eg theta/T)?

 

Furthermore I would like to have an answer on how I get to laplace transforms (ODE) with only "s" in the output, if I type like this:

laplace(J*(diff(theta(t), t, t...

  Can I dowload the Iterator package and use it with Maple 12? Thanks.

Hi, I cannot solve the 2 implicit functions with 2 unknown (m,n) simultaneously (please see attached maple file). Note: m and n are real numbers.

May I get some advice please? Many thanks.

 

 

 

Is there a way to swap the names of two Arrays without creating unnecessary copies?

 

The scenario is as follows. I want to repeatedly apply a function to a large Array. The new value in each cell depends on seveal cells of the old Array.  So on each iteration I need to keep track of two Arrays: A_old and A_new. At the end of the iteration I would like to swap A_old and A_new efficiently. This way I will only need the memory for two Arrays and will...

hello guys , i have a 3D dynamical system , what can i do to have its phase space in poincare coordinates ? thanks so muchmaple.mw

While expanding a lengthy expression I get these in mein series expansion

ln(e)^4*cos(argument(e)/z)^2

I guess e is just exp(1) so why does maple not simplify it to 1 ?

and what shall arg(e) mean?

is it zero?

Hello,

it is more or less my first time using maple for my research. During my mesurements I collect data and store those in an excel sheet. The I made calculations row by row.

I figured out how to import the excel sheet and calculate row by row. Maple calculates the correct results, but how can I easily store the results again, for example row by row in an excel sheet or csv?

This is my code:

> restart;#Range of the Matrix A1:KXXXXprint(??);

Hi, I want to know how to change the rectangular form to polar form, and how to manipulate the operation of them, for example the picture below. The angle of polar form contain radian and degree, how to represent them in Maple?Thank you.

 Can't copy from Maple worksheet and paste here in the Mapleprimes text editor. It's very cumbersome when one needs to detail technical examples. Is there a way to copy and paste?Thanks

Hello, I have been trying to complete a Maple homework assignment for my Caclulus class. I have been stuck on several problems for several days now and I was wondering if anybody could help me. Here are the questions on the assignment that I am stuck on. I know how to do these problems by hand, but I can't seem to figure out the roper commands to do them in Maple4. Given r(t)=(tsin(Pi(t)))i+(t)j+(tcos(Pi(t)))k over the interval [-2Pi, 2Pi}......    a. Find (dr/dt...

 I obtained a count of 7 with the command: stirling2(4,2) . How do I get a list of the 7 partitions? Thanks.
