Prerequisite help with Math etc...
I wish we were taught Calculus when I was at school (in UK)...
For all the other's who have muddled through the difficult Math, here are some pretty good videos that I have started watching to get to grips with the more complicated aspects of this course: Highlights of Calculus  Gilbert Strang So far I seem to be doing okay on the questions where the Math can be modelled, but things like "set theory" etc, I simply don't have enough Math knowledge to tackle. Anyone else know of any other good resources etc which you have/think may be useful/beneficial for use with this "Learning From Data" course?

Re: Prerequisite help with Math etc...
Online textbook covers a huge chunk of the math used in computer science and courses such as this one. Good for review or finding out something new:

Here is a free online tool for help with symbolic calculus http://mathomatic.orgserve.de/CGI/math.php This script finds the partial derivative but in a "simplified" form:
(u*e^v+2*v*e^u)^2 differentiate u

Munchkin thanks, downloaded the first document, looks very good.
Keith, thanks for the link, was looking for something like that a few months back. It is brilliant, I wish I'd seen that before doing q4... confirms my working though. A great proofing tool. Do you know if I can use that tool to explicitly give me values of u and v (so I can proof translations)? The best I found was to use the command "calculate" which gives a more user friendly formula (easier to plug into code).

Re: Prerequisite help with Math etc...
Keith, your formula above should have been:
(u*e^v2*v*e^u)^2 Caused me a bit of initial confusion lol. That'll serve me right for not proofing myself.

Re: Prerequisite help with Math etc...
Whoops, sorry about that! Too bad that copy and paste doen't work well between many programs resulting in typos that waste time and cause confusion.

Re: Prerequisite help with Math etc...
If your calculus is very rusty, like mine, I suggest using wolframalpha to check your answer for the derivative
