Minimum distance between two curves (2 Viewers)

[oly1991]

It's funny how you made an absolute fool out of yourself =D

One word for you mate: Novice

i wouldn't call him a novice the guy is quite skilled at maths just by looking at all the solutions he has provided on this forum.

he just made a mistake that's all.

Well then he shouldn't act so arrogantly.

Tim, the "minimum" distance you found was only the minimum difference in y values between y=3x^2 and y=2x-1. But the real minimum distance is the perpendicular distance.

I think Drongoski is correct.

No I was wrong; I misread the quadratic as y = 3x^2 - 2x + 1
therefore 'min point' on parabola is now (1/3, 1/3) as shown by undalay

But by fluke the distance is the same = 2/3sqr(5).

Lol, why must every thread be turned into some sort of egotistical rant? -.- Well done Azureus + Drongoski + Undalay, I did NOT see that when I was attempting the question =(
