Interpolation is a mathematical technique used to estimate unknown values that fall between known data points. For example, if you have the temperatures recorded at noon and 2 PM, interpolation can help you predict the temperature at 1 PM by using the values from those two times. This method is widely used in various fields, including science, engineering, and finance. There are different methods of interpolation, such as linear interpolation, which connects two points with a straight line, and polynomial interpolation, which uses curves. By applying these techniques, we can create smoother transitions between data points, making it easier to analyze trends and make informed decisions based on incomplete information.
