Linear Interpolation

About Linear Interpolation Android App

Use this calculator to find an unknown between any two sets of data. This method uses a linear polynomial to interpolate and find the unknown value. This method is especially useful for students, engineers, mathematicians, etc. See definitions below to become familiar with this mathematical method:
Datum: “A fixed point from which a measurement is taken.”
Linear function: “A function whose graph (in Cartesian coordinates with uniform scales) is a line in the plane.” For example, f(x) = ax + b where a and b are constants.
Linear interpolation: “A method of curve fitting using a linear function to construct new data points within the range of a discrete set of known data points.”
