Solved Example Problems
The process of finding the value of x for the corresponding value of y is called inverse interpolation.
Lagrange's Inverse interpolation
The
process of finding the value of x for the corresponding value of y is called
inverse interpolation.
In
such a case, we will take y as independent variable and x as dependent variable
and use Lagrange's interpolation formula.
Taking
y as independent variable.
Formula
(1) is called the formula of inverse interpolation.
