Extract

If we consider a set of values a0, an, an and a set of equidistant points x = a, a±nw, there are many interpolation formulæ which give functions assuming the values a0, an, an at the points x = a, a + nw, anw respectively. The function with which the present note deals is, writing π/w = m,
