For example, the Beatles interpolated part of their early hit “She Loves You” into the closing moments of their later hit “All You Need Is Love.” In mathematical contexts, to interpolate is to estimate the values of data or a function between two known values.
It is often required to interpolate; that is, estimate the value of that function for an intermediate value of the independent variable. A closely related problem is the approximation of a complicated function by a simple function.
Linear interpolation, also called simply interpolation or "lerping," is the ability to deduce a value between two values explicitly stated in a table or on a line graph. While many people can interpolate on an intuitive basis, the article...
