The linear interpolation method for locating a root in a given interval is a simple extension to the change of sign method.

The following video example demonstrates this method.

Example:

  1. Find an approximation to the root of x+ 2x – 2 = 0 using linear interpolation twice over, given that the root lies between 0 and 1.
