Directional derivatives – something new again?
14 July 2011 / Krystian Karczyński
Calculating directional derivatives as a subject to be covered (i.e. to be passed) is actually right after partial derivatives of functions of many variables, which most students cover in the second semester.
However, this is a topic rarely taken up that I did not include it in my Partial Derivatives Course and often enough that I will post it on the blog - for the benefit of those who need to learn directional derivatives and those who are simply curious about what's up. However, I would like to point out that, as in the Courses, I will focus today almost exclusively on practice ("how do I do it?") and not on theory ("what am I actually doing?").
