PARAMETRIC EQUATIONS & POLAR COORDINATES
We have seen how to represent curves by
parametric equations.
Now, we apply the methods of calculus to
these parametric curves.

PARAMETRIC EQUATIONS & POLAR COORDINATES
So far, we have described plane curves
by giving:
y as a function of x [y = f(x)] or x as a function of y
[x = g(y)]
A relation between x and y that defines y implici

Later in this chapter, we are going to use
vector functions to describe the motion of
planets and other objects through space.
Here, we prepare the way by developing
the calculus of vector functions.

In this section, we will:
Develop the formula for the area of a region
whose boundary is given by a polar equation.
