- Assignment 2 is ready to be handed back today.
Solutions are posted in the usual place.
- One common Maple mistake surfaced in this assignment
last term, which is worth commenting on here though no-one
made this mistake this time (well done!).
f(x) := sin(x);

What this does is create a procedure called f, and assign an entry to its*remember table*. Thus f(x) will return sin(x). f(3) will return f(3). That is, unless you type exactly f(x) you will not get what you thought you typed. Instead, use operators:f := x -> sin(x);

or expressionsf := sin(x);

Otherwise results can be quite unpredictable.

Today's topic: polynomials in Maple: GCD, resultants, the Hurwitz criterion.
