Rapid Recall
- Find the area of a parallelogram whose edges are parallel to the vectors $(1,2)$ and $(3,4)$. (Use the $|ad-bc|$ rule.)
- Give a vector equation of a line that passes through the point $(1,2)$ and is parallel to the vector $(3,4)$.
- Give a Cartesian equation of a line that passes through the point $(1,2)$ and is parallel to the vector $(3,4)$.
As groups
- Draw the polar curve $r=2\cos3\theta$ for $0\leq \theta\leq 2\pi$.
- Find the area of a triangle with vertices at $(0,0)$, $(-2,1)$, and $(4,3)$.
- Consider the polar curve $r=\frac{2\theta}{\pi}$.
- Draw the curve (did you get a spiral) for $0\leq \theta\leq 4\pi$.
- Compute $\frac{dx}{d\theta}$ and $\frac{dy}{d\theta}
- Set up an integral formula to calculate the length of the curve for $0\leq \theta\leq 2\pi$.
