1. ## Inverse vs. Reverse

Just as the subject says: what is the difference between the word 'inverse' and 'reverse'?

reverse: opposite direction; backwards
inverse: change in order

I don't buy this; when things are 'in inverse proportion' order doesn't come into it - it means 'when one gets bigger the other gets smaller and when one gets smaller the other gets bigger'.

Inverse is opposite in order or proportion. In language inversion is when the predicate comes before the subject. So it's about order.

order:
logical arrangement of separate elements

f(x) = 5x

x-->f(x) = (0;0); (1;5); (2;10); (3.14;5*3.14);....

inverse:

x = 5f'(x)
f'(x) = x/5

x -->f'(x) = (0;0); (5;1); (10;2); (5*3.14;3.14);...

Can you see the change in order, Bob?

Oh, that kind of order.

PS That last post wasn't meant to suggest I knew in detail where the discussion was leading. My maths is 'Best Before End May 1968'. It was just that I recognized what sort of 'order' was involved; it was an 'order of magnitude' sort of reply.

Same here. To add insult to injury, I teach maths.
