How do i solve for C? C = 23481726526273849572 ^ 10982375684973 mod 2984652746 M e n I was told the proper command was C := M&\^e mod n; OR C := Power(M,e) mod n; but neither work.

## Exporting and Importing with Excel...

Hi, I'm somewhat new to Maple and I have a problem that I can't figure out. I have an excel file that performs a series of calculations and I would like to plot the values from a single cell as an input parameter cell is varied. Is there a way that I can use Maple to do this? I tried exporting a value to the input parameter cell, and then importing the value from the output cell, but the value that gets imported isn't changing as I vary the exported value. If I open the excel file itself, the values have changed, so I know the export is working, but it doesn't seem to want to import the new value from excel.

## How to simplify a complicated (with maple,maybe,bu...

In Maple,how can I simplify an expression to a better form ? Like this,for example: a^2+2ab+b^2 -> (a+b)^2 a^3+3a^2*b+3a*b^2+b^3 -> (a+b)^3 As I know,simplify() only groups similar terms and some simple computations, doesn't it ? So , how can we do like the above ? I think that Maple must be able to do that , because it's a required utility of a CAS.

## In Maple 11, the notation for tensors in the Physi...

I use Maple-11 , especially the Physics and Tensor, Diff Geometry packages, in a worksheet. How do I get to create tensors with a uniform notation for covariant and contravarint indices using Create or Define ? I need tensors like, for instance, A superscript i, subscript j, as in McCONNELL (Abs. Diff Calculus) How do we get a uniform notation for tensors on a worksheet using either the Physics or Diff Geom package ? Are Create and Define equivalent ? Can thye be made to print tensors with the same format, or appearance? Please give me a few examples. Thanks. Radhakrishna Prof Physics

## Differential Algebra package

by: Maple
How do I get anything to work with the differential algebra package with(diffalg)? Maple does not recognize its own commands and then makes things worse by crashing my computer. I've had to pull the plug on my computer at least twice. For instance, whenever I try to type "differential_ring" as soon as I type the underscore, Maple puts me into a subscript mode. Also, there seem to be TWO packages of commands for everything: e.g. with(linalg) and with(LinearAlgebra) with(diffalg) and with(DifferentialAlgebra) which overlap tremendously! Also, sometimes [[a,b],[c,d]] is recognized as a matrix and sometimes it is not. Changing it to

I have get a functionsystem:   ## Need help with setting up a range...

I apologize to ask this rather simplistic question, but I am very new to this. I can plot a function such as plot(10*x3, x=1..5); BUT what if the range is only specific points such as x=1, 0,07, 8? What is the syntax for this range?

## Swapping rows?...

I'm trying to swap rows of a matrix using the LinearAlgebra package not the linalg one. is there a easy way of doing this?

## How can i change Document Mode to Work Mode...

well, i'm using a Evalution Version Maple .i spend one day time to find how can i change Maple to Document Mode but finally failed. May be Evalution Version doesn't have Work Mode and only have Document Mode? :(

## Summing lists of lists of numbers...

I have a list of lists. The number of lists I have is unknown (though always a positive integer) and the number of elements in each list is unknown (though, again, always a positive integer). Some examples: [,]; [,,[5,1]]; [[3,4,1],,,[6,7]]; I'd like to form a list of all possible sums formed from one element of each list. The lists of sums from the examples above would be ; [13,9]; [13,14,11,14,15,12]; The order doesn't matter, and repeated elements don't matter. I can form these lists when I can control the number of lists in the large list and write an explicit nest of for loops. I figure there's got to be a more elegant and powerful way of producing these sums.

## x(T) vs z(T) vs u...

Hi I've got 2 functions of a variable T [x(T) and z(T)] and a varying parameter u and i want to plot x(T) and z(T) against each other and show how the curve changes as u varies (hope that makes sense) how can i do that?

(I think this was posted in the wrong section of mapleprimes.) Hi, I have read the manual on saving to a file many times but it never works for me. I am using Maple 10 on a Mac running MacOS 10.4.10. I have copied the example from the manual and run that and it does work so I am quite confused. Here is what I would like to do: I have a worksheet with lots of definitions,equations, lists, etc. and I would like to have these available on another worksheet. I have tried > save nx; # nx is the name of my worksheet then > read nx; Error, unable to read `nx` I have the same problem with trying to save names e.g.
