So easy when you know the rules

Having worked for two solid days on question 5, I'm calling it quits. There are plenty more fish in the sea - specifically, five other questions to be done by Friday. By leaving question 5 strictly alone until at least tomorrow night I hope to distance myself from it and hence be able to actually do the algebra next time I try.

It wasn't until this morning's tutorial that I found out how to "easily" calculate a directional derivative. Pretty simple really - just apply the Jacobian matrix of the function to the direction vector in question. Ha ha, so easy. Ha.

Having done that and acquired derivatives that even Maple agrees with, I now find myself so egg-brained that I can't simplify the resulting expressions. Enough already.

I have very clear memories of today's tutorial last year - by which I mean the first tutorial for assignment 3 - as it was the last tutorial I attended for the course in 2006. A year ago I sat through it in total confusion. This year I followed everything, asked a question, and even understood the answer!

A year ago I skipped the second tutorial for assignment 3 because I was trying to finish the assignment. I didn't finish it, and that was it.

That's not going to happen this time.

I will! Star for you :)

Amusing that you and Bruce have now both made the same error with reference to the title of this song.

That's no doubt because of the name of the album.
