Section 13.2: Derivatives and Integrals of Vector Functions
Exercise 50
If \(\mathbf{r}(t) = \mathbf{u}(t) \times \mathbf{v}(t)\), where \(\mathbf{u}\) and \(\mathbf{v}\) are the vector functions in Exercise 49, find \(\mathbf{r}'(2)\).
If \(\mathbf{r}(t) = \mathbf{u}(t) \times \mathbf{v}(t)\), where \(\mathbf{u}\) and \(\mathbf{v}\) are the vector functions in Exercise 49, find \(\mathbf{r}'(2)\).
