👉 Interpolating is a process that involves the calculation of the value(s) of an unknown variable at various points in time or space. This can be done using mathematical methods and algorithms to approximate values that are difficult to determine directly, such as the position of a point on a circle or the temperature of a fluid at different times. Interpolating is often used in scientific and engineering applications where it is necessary to find the value(s) of an unknown variable at various points in time or space.
