High order directional derivative

WebDerivatives of higher order can be very time consuming - especially for functions like f (x) = x3 ⋅ e−4x. Evaluating such derivatives become very manageable/time efficient problems by using the Taylor polynomials/series. (a) Write the 10th degree Taylor polynomial for f (x) = x5 ⋅e−2x centered at x = 0. (b) Evaluate the 8th derivative ... WebThe higher-order derivatives in [14] are consistent with the classical Fr´echet direc-tional derivatives, but the sufficient conditions are very restrictive. Even the second-order …
