Rapid Recall
1. Let $z= x^3+4xy+y^2$. Compute $dz$ in terms of $x$, $y$, $dx$, and $dy$.
Solution
2. Write your answer above in the form $dz = (?_1) dx+(?_2) dy$.
Solution
3. Write your answer above as the dot product of two vectors, namely $dz= (?????)\cdot (dx,dy)$.
Solution
4. If $dz=0$, then what does the equation above say about the relationship between the vectors?
Solution
5. What does the vector $(dx,dy)$ represent physically?
Solution
