interpolation methods

Interpolation methods are techniques used to estimate unknown values between known data points. Imagine you have temperature readings at certain times and want to find the temperature at a time in between; interpolation helps with this. Common methods include linear interpolation, which connects two points with a straight line for a quick estimate, and more advanced techniques like polynomial or spline interpolation, which use curves for smoother, more accurate results. These methods are widely used in fields like science, engineering, and data analysis to fill in gaps and make predictions based on existing data.
