Enter the coordinate points and slopes of two dependent lines into the calculator to calculate a third value P, using bi linear interpolation.
Double Interpolation Formula
The following equation can be used to calculate a value from a double interpolation.
What is double interpolation?
Double interpolation is a term used in mathematics to describe values that are dependent on two different variables or functions. For example, if you a an object C that relies on the states of both A and B, and the states of A & B can be represented by functions, then the states of C can be calculate using double interpolation.
