WebCubic Hermite Interpolation • Develop a two data point Hermite interpolation function which passes through the func-tion and its first derivative for the interval [0, 1]. • Therefore and . • We must impose constraint equations (match function and its derivative at two data points). • Therefore we require a 3rd degree polynomial. 0 x f f 1 WebBecause of its oscillation property the LAGRANGE polynomial is not suitable to interpolate the given experimental data. Thus, the spline interpolation has been discused as an alternative approach. song to my heart
