 | I have been out of school now for about 30 years, and since my
employment has mostly been in sales I've forgotten pretty much
everything I ever learned about mathmatics.
I was wondering if there were online sources that could help bring me up
to speed? I don't think I need to see anything past about year 10 :)
This all came about when a friend asked me how long the 'sloped' side of
a triangle was when the 'right-angle' sides were 6cm x 8cm. I guessed
about 10cm which turned out to be right, but I couldn't remember how to
work it out accurately:)
TIA

Well your question above was solved using pythagorus theorem.
The square of the hypotenuse (the long side) is equal to the square of
the other two sides.
100 = 36 + 64
therefore the length is 10cm (the square root of 100).
As for a good website, I am tackling math at university to actually
teach math, for me this meant getting my sin/cos/tan stuff up to
scratch. I found this website which covers alot of the practical basics.

When you get through that one, you will probably have a better idea of
what you might be interested in next (ie calculus, stats etc)

Thanks for the response, that page looks to be exactly what I need:)
Cheers!

Heh, didn't spot the typo in the subject line until I saw my post.
