Finding other Polar Coordinates
The attachment is an example of a problem that I have to do, but I don't understand how the (r, θ), applies or can apply to (a), (b), and (c).

An explanation of how to find additional polar coordinates would be greatly appreciated!

Thank you!

Re: Finding other Polar Coordinates
all of these give the same polar coordinates ...

$\left(4,\frac{5\pi}{3}\right)$

$\left(4,\frac{5\pi}{3} - 2\pi \right)$

$\left(-4,\frac{5\pi}{3} - \pi \right)$

$\left(4,\frac{5\pi}{3} + 2\pi \right)$
