Is there a straightforward procedure to have a radical appear on the plot of a function? E.g, how can one display (2, sqrt(2)) in the plot but with the actual square-root symbol appearing. I've read in the knowledge base about the use of textplot. However, the routine is limited to exponents.

This is a program discribing the dynamic behavior of a N pendelum system. When I tried to comparae the result of different initial conditions, I found that every time i run it, the graph will be different.

I know that double pendelum system is a typical chaotic system, is this the reason why i have different result for each time?

Here I attach the file, but plz rename it to ***.mws file before run, b/c i wrote it in maple classic worksheet.

has someone a sheet about percolation theory ? I put a very simple one on my blog: percolation

I can pointplot a single curve if I select a single element from the list below. Is it possible to use all the elements of the list and plot several curves on the same graph?

If I have the X and Y variable all done up and I am trying to find a way to figure out if their is a way to make up a quadratic equation with maple. and can maple find the inflextion point of this curve ? Any help would be appreciated. Thanks Jp

I have a procedure that will run fine in Maple 8 but gives an error when it is run in Maple 9.5. The error is a "cannot solve error". Are there any known issues that may lead to this type of problem? Thanks.

Is there a way to do a Symbolic Computations under Max-Plus Algebra? For instance, linear algebra computations under under Max-Plus Algebra. I would like to appreciate any comments on it.

I need to search for primitive polynomials of degree n over finite fields GF(q), where q is a PRIME POWER. I have major difficulties doing that, especially when I wish to fix one of the coefficients of the polynomial. On the other hand, polynomials over GF(p) pose no problem. Does anybody have any experience in this? PLEASE HELP!

Hi, guys could you please let me know how I can find this definite integral through Maple? int(exp(-I*x)/cosh(x)^3,x=-infinity..infinity); or int(exp(-I*x)/cosh(x)^2,x=-infinity..infinity); thanks a lot Sayed

I'm going through Francis Wright's COMPUTING WITH MAPLE. c2002, and based on Maple6. can anyone explain the reason for the output that I get just for the last statement alone dealing with the change of base for logarithms ? >

I would like to construct a maplet to evaluate different objects in general relativity, say for example , metric,covaliant derivative and so on. Please help me with the procedure or a sample maplet.
