Just to confirm, is the directional derivative of a vector valued function calculated as Lu ? where L is the Frechet derivative , and u is the unit vector in the direction.(adsbygoogle = window.adsbygoogle || []).push({});

There seem to be a lot of sources for a real valued function's directional derivative, but very little on vector valued function in Rm.

it says DuF(directional derivative) = lim (F(x + tu) - F(x)) / t as t->0

if F is diff'ble, then -] L , then just set h = tu, we get the desired result?..
