What is the distance between #(3, 2, 1)# and #(0, 4, –2) #?
The distance is
The formula for the distance for 3-dimensional coordinates is similar or 2-dimensional; it is:
We have the two coordinates, so we can plug in the values for
Now we simplify:
If you want to leave it in exact form, you can leave the distance as
Hope this helps!
