This page lists the in-recitation problems worked on during MATH 22 (Calculus 3) in Summer 2012 at MST.
Notational convention: in your textbook, vectors are bolded and look like this: $\textbf{x}$. For better readability on the computer, we use instead the notation $\vec{x}$ for vectors on these pages.
