Q1: What, in your own words, is the difference between a partial derivative and a directional derivative? How are they similar? Give a particular example to illustrate your explanations (choose some function z=f(x,y)) Q2: Given a surface z= f(x,y), a point (x,yo) in the domain of f, and a unit vector i pointing some direction in the xy-plane, what does it mean if D,f(x,Y)=0? Be as specific as possible.
