*d*from the origin to that point) Using the distance formula, I am getting a 0. Is this correct? - January 30th 2013, 12:30 PMebainesRe: Distance formula
It should be obvious that the distance between the point (1,1) and (0,0) is not 0. The formula for distance betwen points A and B is:

Here point A is and point B is . - January 30th 2013, 12:54 PMgoldbug78Re: Distance formula
so 2 squared then?

Not 2 squared, but

**square root**of 2. - January 30th 2013, 01:03 PMPlatoRe: Distance formula
