I have to find the distance for the the points -1,1 at 135 degrees. (Find the distancedfrom the origin to that point) Using the distance formula, I am getting a 0. Is this correct?

*d*from the origin to that point) Using the distance formula, I am getting a 0. Is this correct? - Jan 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:

$\displaystyle d = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}$

Here point A is$\displaystyle (x_A,y_A) = (1,1) $ and point B is $\displaystyle (x_B,y_B)=(0,0)$. - Jan 30th 2013, 12:54 PMgoldbug78Re: Distance formula
so 2 squared then?

Not 2 squared, but

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