Calculate the area of the parallelogram spanned by the vectors $\vc{a} = (3, -3, 1)$ and $\vc{b} = (4,9,2)$. Solution: The area is $\| \vc{a} \times \vc{b}\|$. Using the above expression for the cross product, we find that the area is $\sqrt{15^2+2^2+39^2} = 5 \sqrt{70}$.
In this first exercise, you will study the moose on Isle Royale. before the arrival of wolves. The lab simulates the arrival of the. group of moose that swam to the island and rapidly reproduced. to form a large population.
