Pre-requisite help with Math etc...

[itooam]

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?

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:

A primer on conditional probability.

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).

Keith, your formula above should have been:

(u*e^v-2*v*e^-u)^2

Caused me a bit of initial confusion lol. That'll serve me right for not proofing myself.

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.

Here's a useful site for calculus, and for plotting:

If your calculus is very rusty, like mine, I suggest using wolframalpha to check your answer for the derivative
