I am playing around with tetraroots in Maple and I've encountered a situation
where I think I am asking a bit too much of its iterative solver:
Code:
#tetration power tower

Some time ago, I needed to transform output from codegen:-maple2intrep
to a form where function and table applications will stay unevaluated.
As advised in the maple2intrep help, I tried to use the (formally
undocumented) routine `tools/rename` but found it chokes on the

I have a function f defined in an interval [0,a].  Is there
a way to extend f to the entire real line as a periodic function
with period a?

In maple11 I have made this:
solve((2+I)*z-(2+3*I));
which gives:
7/5+4/5*I

"int(1/(1+a*cos(x)),x=0..Pi/2) assuming a>0;"
cannot give me a explicit result? what should I do for a explicit one?
thank you.

Is there a way to save data (output results) into a file in order read
and use them into another Maple worksheet? As a result I have a few
sets of the type f[6] = -.1107309604e-2,a[4] = -.3123268129e-1,f[5] = .
2537252701e-1,e[6] = -.1174432282e-1,e[1] = -.8421569996e-3,a[2] = -.

I need to change the output format of the Maple. If found in the
"help" that for that I need:

Character Notation, Typeset Notation, or 2-D Math Notation. The

How do I make a picewise function for x^2 over this interval:
]-infinity; -4[ U ]-4; -1[ U ]-1; infinity[
I have tried this:
f:=x->piecewise(-infinity<x and x<-4 or x>-4 and x<-1 or -1 < x and x <

I have got the following problem:
I need to calculate (A + B*cos(x) + C*sin(x))^3 with the objective of
computing the coefficients of the polynomial obtained by writing
the above quantity in terms of sin(x), cos(x), sin(2x), cos(2x) and so

I use Maple 9 in RHEL 3 with 2.4.21-47.EL. And I've installed NVIDIA
Driver for my GeForce2 MX 400 GPU.
If I use any plot functions to draw something in classic worksheet, Maple
will be terminated with a line of error:

I get this error:
f:=x->(8*x^4+2*x)/(3*x^4-7)-8/3;
%;
Error, `)` unexpected

In maple 11 I have:
read "file1.m";
read "file2.m";
read "file3.m";

When I try to execute the last line in this maple sheet nothing happens:
restart;
with(LinearAlgebra):
VUP:= <0,1,0>; VPN := <4,3,0>;

is there any way to convert structured SQL-Datas to Maple 11? Or vice
versa: Is there databasing supported by Maple 11?
Thanks and regards,

I am working on the numerical recovery of functions of functions with
discontinuities.
Here is an example:
