## randperm in MapleTA produces always the ...

I use combinat[randperm] in MapleTA to get random permutations. But everytime I call the corresponding question bank, I get the same sequence of permutations. Even a randomize();with(combinat);randperm... doesn't change this behaviour but every single student should get different homeworks. Any idea?

## mathfrak symbol in LaTeX question bank...

I usually write my question banks with LaTeX.

The manual says:

The LaTeX package epsfig is loaded by default. The ed package is required. Other standard LaTeX packages, for example, amsmath, can be included using the \usepackage macro.

But if I start my document with

\documentclass[12pt]{article}
\usepackage{amsfonts}
\usepackage{ed}

and use for example \mathfrak{P} I only get a blank box instead of this symbol in my question bank.

## constant of integration and maple graded...

Hi, I'm just writing a question bank for some simple integration exercises. This causes some problems with the constants of integration and the syntax of maple graded questions: If I ask for int(1/sqrt(x^2+4),x) one student could give the correct answer ln(x+sqrt(x^2+4)) and another one could give arcsinh(x/2), which is correct as well but with another additive constant. In formula mode one of these results would not be acknowledged as correct. Therefore I tried to use maple graded questions and compare the differentiated results. I used the syntax like in the manual at http://www.brownstone.net/support/edu/authoring/index.html
