In the island nation of Talura, people have begun using dried cacao beans as money. These beans are used in local trade and prices are quoted in beans. However, beans are perishable and subject to rot or pest damage, and large transactions require bulky sacks of beans. Using the functions of money — medium of exchange, unit of account, and store of value — analyze whether cacao beans in Talura serve each of these roles effectively. Support your analysis with evidence from the scenario.

Let r→(t)=\vec{r}(t)=. Write the parametric equations for the tangent line to r→\vec{r} at the point where t0=0t_0=0.

You are herding frugs up a trail on a hill (coincidentally, the hill is shaped like a perfectly round paraboloid). As you reach the most south-western part of the mountain trail the evil wolf Eerg appears and chases some of your frugs up the trail! Luckily, you know a shortcut. Write a vector (with numbers for full credit) that describes the direction you go to beat Eerg to the top and recollect your frugs. For the sake of this problem, let’s assume you run just as fast, regardless of the incline. The answer doesn’t depend on the equation for the mountain, but if you would like an example just use f(x,y)=25-x2-y2f(x,y)=25-x^2-y^2 and the points (-3,-3)(-3,-3).

Let F→(x,y,z)=\vec{F}(x,y,z)=. Find the divergence, ∇∙F→\nabla\bullet\vec{F} and the curl, ∇×F→\nabla\times\vec{F}.
