We're ready to practice using polar coordinates.
Polar functions are the perfect opportunity to practice. We can think of polar functions like a bear itself—a polar bear in this case. We need to wrangle the polar bear for our confrontation with the calculus bear.
First, a few basics. A polar function is a function described by an equation of the form
r = f (θ).
The values of θ to be used will often be specified by an inequality α ≤ θ ≤ β.
The polar function r = f (θ) can also be described by the parametric equations
