Laplace – Everett’s Formula

Formula:

F(u) = {  u  f( 1) + u(u – 1)(u + 1) ∆² f(0)

             1i                   3i

    + u(u – 1)(u + 1)(u – 2)(u + 2) ∆⁴f(-1)}

                             5i

   +{ w  f(0) + w(w – 1)(w + 1) ∆²f(-1)

       1i                     3i

   + w(w – 1)(w + 1)(w – 2)(w + 2) ∆⁴f(-2)}

                           5i
