Yeap. You've got me... I tend to like english humor like Monty Python.

Then some people think I am cocky when I do long derivations on paper with ink
instead of with a pencil (or is it pen, darn language!).

Run Maxima! I do.

I have had a rought start as well, but it takes experience and eager to learn
to pick up on the nitty-gritty to understand what to really expect. I have had
good experiences in getting the result I wanted in the end when doing filter
design. Some of it lies in care of propper measuring I might add.

The trouble with math is that the way it is taugth it is booring and not very
forgiving. I've developed my own style on how to approach it which makes many
of the things fairly nice from a comprehensive side of things...
