Exercise 3.9: distance

Added by: Marty Stepp on 2010/10/03
Keywords: parameters, Math

Write a method called distance that accepts four integer coordinates x1, y1, x2, and y2 as parameters and computes the distance between points (x1, y1) and (x2, y2) on the Cartesian plane. The equation for the distance is:

distance equation

For example, the call of distance(1, 0, 4, 4) would return 5.0 and the call of distance(10, 2, 3, 5) would return 7.615773105863909.
