How can I plot functions easily?

I’ve used the full version of Mathematica and it’s a tour de force. It’s also massively more sophisticated than most people need (as well as hugely overpriced).

So try this cut-down online version.

Try typing in  Plot sin (x^2) / e^x or something…

 

What else can I read?

There are very few books which explain things with the degree of clarity I seem to need.  Even the very best authors sometimes use imprecise English and expect the reader to fill in the gaps using ‘context.’  I seem not to do context. 😉

I’m providing a list of publications below which are worth reading. If you want to really understand the subject matter, I suggest working through at least two on each subject. Some of this stuff is University level, so expect to come out with some new questions of your own!

Melanie Mitchell –Complexity

John Gribbin –Chaos, Complexity…

Peter Atkins –Galileo’s Finger

 

What is the future of education? -Khan Academy

Sometimes, if you aren’t getting a new concept, it’s really useful to hear someone else’s version.

Here is a video about Khan Academy. This represents the future of education and is also a great place to get an additional perspective on a wide variety of interesting topics.
