An easy and novel Introduction to Imaginary Numbers

This is my attempt to explain Imaginary and Complex Numbers by using the idea of rotations - it is supposed to be accessible to anyone wanting to discover what Imaginary numbers actually mean, without going deeply into any algebra.

This is my first video, so it's not perfect - in particular, my laptop mic is pretty dreadful, and the pace of the video does go a bit fast in places - it might well be necessary to pause/rewind to be able to absorb everything!

I hope you enjoy it, and please give me any feedback/ask any questions below!

EDIT: Since making this video, some people have pointed me to: http://betterexplained.com/articles/a-visual-intuitive-guide-to-imaginary-num... - it seems to explain imaginary/complex numbers in a very similar (and perhaps clearer!) way - so give it a look!

Thanks man. More videos please!

@FullWaveElectronics - I'm glad everyone likes it so far! I'm rather busy at the moment, but I might try and make another one over the Christmas period. Any topics in particular you'd like me to have a look at? Maybe more complex numbers, or some other part of maths completely?

they've started setting this video for homework at Ags! haha good video, cheers man!

Very helpful, thank you.

[altomatomer]

very clear explanation, thanks.

[ApocalypseHare]

Actually.... this has been very helpeful I'd been trying to figure that out for so long now

[LRAJack]

An interesting approach to complex numbers - will show to my Further maths students tomorrow as we're currently studying them!

Very clearly explained.

Thank you :o)

[jiddey]

Wonderful !!!

Thank you very very much
