## Testin Statistical Hypotheses...

Hi there, I've just started using Maple, and must say it is a real good tool - powerfull!!! But to the point, I have created a 'simple' procedure for determinig the shape of UMP Unbiased test for testing H0: the probability 'p' of getting "1" in the Bernoulli scheme is

## Plot charfcn...

I, i need to plot a z-trasformed function (discrete function), that has some "Dirac" (isn't a real Dirac function) points. How I have to do? This is an example: f:=1/2*(charfcn[2])(k)-3/4*(charfcn[1])(k)-3/8*(charfcn[0])(k)+3/8*2^k;

## How do I plot a 4-D object (pentatope)?...

It's according to my project, again. I want to plot a pentatope (4-simplex) with Maple. I've tried using plot3d with animate but it's look doesn't work. Thanks for your help.

## Published/online articles about Maple TA?...

I'm trying to find some articles on people's experiences (good, bad, indifferent) about their use of Maple TA. Does anybody know of any good ones? Some time ago I could download articles from the Maple conferences in pdf form, but when I went looking more recently I couldn't find them Thanks, Alasdair

## Efficiency in Mapel T.A. algorithms...

Nowadays i am trying to program a kind of computer algorithm to generate a random mathematical formula, and I'm having an argument with another mapleTA programer, the question is this one: What is more efficient, have a question for all the types of formulas with random variables or have only one question with a code like:  $a = range(-5,5);$ea= range(1,5); $eb= range(1,5);$ec= range(1,5); $eq1 = switch(rint(7),maple('$a*x^$ea*y^$eb*z^$ec'),maple('$a*x^$ea*y^$eb'),maple('$a*x^$ea*z^$ec'),maple('$a*y^$eb*z^$ec'),maple('$a*x^$ea'),maple('$a*y^$eb'),maple('$a*z^$ec')); 

## Need help starting...

can anyone help me start with how do I solve the equation sqrt(1 - y^2(t)) with initial value y(0)=0 and y(t) between -1 and 1 and t between -pi/2 and pi/2

## Exporting Maple Worksheet to LaTeX...

Hello there! I have a maple code that is approximately 300 lines. There are no graphs printed and I would like to export this as a LaTeX code. I choose export under File and save the file as "test.tex" I have installed all the maple packages and refreshed fndb. The problem is that LaTex is not able to run the document. I get the following error: ! Argument of \end has an extra }.

## Tabs - or lining up columns...

Hi Am trying to tidy up a printout of two columns in M version 7, such that the second column is lined up. Using the tab character \t in the printf statement does not seem to work - it just shifts a fixed number of spces, rather than go to a tab stop position. The following Maple code is very klutzy: however its redeeming feature is that it does work. Sample Maple code: #Create a long string of spaces (26 spaces between " ") aspac:=CharacterMap( "ABCDEFGHIJKLMNOPQRSTUVWXYZ", " ", cat(a,a) ); #NB a is the first 'word' - see output below #spac is a string of spaces to ensure alignment

## solve a recursive equation in 2 variables...

Hi Maplers: I'm probably spoiled, but maybe Maple can actually solve the following type of problem and I just haven't figured out how. Solve a recursion equation in two variables: f(m+1,n+1) = some expression involving combinations of f(m,n) etc. I am impressed with "rsolve" that magically finds solutions to f(m+1)=... i.e. a single variable. With great effort I have managed to figure out my 2-variable problem using generating function techniques, but perhaps Maple can do the whole thing in one great big single step. Does anyone know if such a thing exists? I can't find anything in the Help.

## numerical differentiation / fdiff...

Is there a way to use fdiff for functions, which allow only numerical input? It seems that fdiff is sending symbolics and that would not work in my case of interest (and I want to avoid to code such stuff, especially how to get the appropriate step size automatically ...). Related to Maple I only find this (general) source, but no according paper: M. Monagan, E. Cheb-Terrab A numerical differentiation routine for computing single, multiple and partial derivatives to arbitrary precision. This enables us to compute numerical values of derivatives of special functions for whic

## how to print a matrix...

I would like to know how to print a matrix using the TextBox command from Maplets, because always print a message "Matrix(3, 3, [ [ 1,1,1],[1,1,1],[1,1,1 ] ], datatype = anything, storage = rectangular, order = Fortran_order, shape = [])", for example. Another doubt is if it's possible to print text and equations using the MAthMLViewer without erasing the previous print in the Maplets (to each program output a line is added in the MathViewer). I would be grateful for any hint. Adriene Pfeifer restart:with(LinearAlgebra):with( Maplets[Elements] ): test:=proc() local M; M:=Matrix(3,3,1);
