Draw figure demonstrating where all three domains of f,g,and h intersect. The domain of $\vec{r} (t) $ is the domain when all three functions are valid. \subsubsection{Vector Functions Example 1} Find ...

$\overrightarrow{v}(t) = \begin{bmatrix} f(t) \ g(t) \ h(t) \end{bmatrix}$ $t \to \begin{bmatrix} f(t) \ g(t) \ h(t) \end{bmatrix}$ $t \to f(t)\overrightarrow{i} + g ...
