When we take partial derivative, we keep one variable constant and partially derivative with other variable.
For example, here in this question both the functions have been partially derivated with respect to x, while keeping y constant.

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.
