Let , , , , be points in the plane, with all the distinct. The Lagrange interpolating polynomial is the polynomial of degree given by the formula
Its graph passes through the points , , , ,. This formula was described by the English mathematician Edward Waring in 1779, rediscovered by Euler in 1783, and published by Lagrange in 1795.
