What is interpolate definition?

Interpolate, in mathematics, refers to estimating or finding values within a set of known values or data points. It involves using existing data points to estimate values for unknown data points. Interpolation is commonly used in various fields including engineering, physics, and finance. There are different methods of interpolation, such as linear interpolation, polynomial interpolation, and spline interpolation. The choice of interpolation method depends on the nature of the data and the desired accuracy. Interpolation is the opposite of extrapolation, which involves extending data points beyond the known values.
