Some useful or just funny math videos

Here are some useful videos i've found: - This is a useful and clever multiplacation method using lines - An even more useful method of multiplacation! -This is about evaluating logarithms and is very well expalined - This is a great song sung by Tom Lehrer about "New Math" - The best song ever for learning pi to 30 decimal places!!! - This is called lose yourself in the digits and it's by pi diddy It's really funny and it's instead of eminem singing "Lose Yourself". The lyrics are great!!!! - This is about the monty hall problem and it explains it very well - One of the funniest songs ever. It's called "What you know about math" - Very funny video about a math test

I've forgoten how to do hyperlinks so if anyone knows it might make it easier big_smile

Re: Some useful or just funny math videos

I edited links into the post for you. For future reference, there are two main ways of making links.

The easier one is just to encase the link in [url]tags.
e.g. [ url ][ /url ] (without spaces) gives

Alternatively, you could put a description of the link by doing [ url={link} ]{description}[ /url ].

e.g. [ ]Search engine[ /url ], without spaces, gives Search engine.

Why did the vector cross the road?
It wanted to be normal.

Great links, thanks.

Re: Some useful or just funny math videos

Mnemonics is not a good way to learn the digits of things like the natural logarithm (e) or pi. I can recite pi to a thousand decimal places, and e to around 720 or so, and I did not use any special methods other than my memory.

Memorising e is quite easy; Here is a guide for only the first 15 decimal places of e ...

e ≈ 2.718281828459045 (to 15 decimal places)

We all know e as approximately 2.7 (or 2.71). The next bit is simple ... 1828 twice. That's all it is. Two-point-seven ... one-eight-two-eight-one-eight-two-eight. Next are the angles of a perfect right-angled isosceles triange ... 45° 90° 45°, in that order precisely. Say that now.

There is actually a factual piece of text for memorising fifteen digits about a president of some country elected twice in 1828 (true story!). I posted it in an 'e' thread in the This Is Cool forum a while back. A year ago I also posted links to pi mnemonics for those who want to memorise pi, for .... whatever reason? smile
