Chapter 9.3, Problem 1E

(a)

To determine

To plot: The polar coordinate $\left(2,\frac{\pi }{3}\right)$ and then find the other pairs of polar coordinates for the conditions $r>0$ and $r<0$.

(b)

To determine

To plot: The polar coordinate $\left(1,-\frac{3\pi }{4}\right)$ and then find the other pairs of polar coordinates for the conditions $r>0$ and $r<0$.

(c)

To determine

To plot: The polar coordinate $\left(-1,\frac{\pi }{2}\right)$ and then find the other pairs of polar coordinates for the conditions $r>0$ and $r<0$.
