Distance[ <Point>, <Object> ]
Yields the shortest distance between a point and an object.
Example:
  • Distance[(2, 1), x^2 + (y - 1)^2 = 1] yields 1
Note: The command works for points, segments, lines, conics, functions and implicit curves. For functions it uses a numerical algorithm which works better for polynomials.
Distance[ <Line>, <Line> ]
Yields the distance between two lines.
Example:
  • Distance[y = x + 3, y = x + 1] yields 1.41
  • Distance[y = 3x + 1, y = x + 1] yields 0
Note: The distance between intersecting lines is 0. Thus, this command is only interesting for parallel lines.
Note: See also Tool Distance.gif Distance or Length tool .
