To find the polar coordinates of (-4,0), you use the formulas:
[r = \sqrt{x^2 + y^2}] [θ = \arctan\left(\frac{y}{x}\right)]
Plugging in the coordinates (-4,0):
[r = \sqrt{(-4)^2 + 0^2} = 4] [θ = \arctan\left(\frac{0}{-4}\right) = \arctan(0) = 0^\circ]
Therefore, the polar coordinates of (-4,0) are (4,0).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
