My Mathematical Genealogy

For a long time I have been planning to work up my mathematical genealogy using “The Mathematical Genealogy Project” site.

We proved the formula of the maximum value of the directional derivative, as well as the direction for which it is maximized. Next time we’ll begin basic optimization theory for functions of several variables.
