distance formula
posted by Scott .
Hey thanks, stupid negative.....
Ok now I'm trying to figure out the distance formula.
the coordinates are (1,3) and (2,5)
So I take (53)^2 + (21)^2
and get 2^2 + 1^2.
so 4 + 1 is 5. so the square root of 5 is the answer?
your second subtraction is wrong
it should be (2(1)^2 which is 3^2
so you should have
distance =√(2^2 + 3^2)
=√13
