In this paper, we study the possibility of using geometrical probability for designing Lagrange interpolational polynomials with quadratical and cubical interpolation by the example of functions of one and two arguments. We considered a one-dimensional element (3 nodes), a triangle (6 nodes), a square (9 nodes), and a triangle (10 nodes).




Keywords: geometrical probability, Lagrange polynomials, quadratical and cubical interpolation, Finite-element method.
