Penjelasan dengan langkah-langkah:
[tex]\bold{r}(t) = \left[\begin{array}{ccc}3\cos(t)\\2\sin(t)\end{array}\right] , t > 0[/tex]
a) Liat di gambar
b)
[tex]\boxed{\boxed{\bold{v}(t) = \bold{r'}(t) = \left[\begin{array}{ccc}-3\sin(t)\\2\cos(t)\end{array}\right] }}\\\\\boxed{\boxed{\bold{a}(t) = \bold{v'}(t) = -\bold{r}(t)=\left[\begin{array}{ccc}-3\cos(t)\\-2\sin(t)\end{array}\right] }}[/tex]
