Why is the first quadrant positive?
In the first quadrant both the x-coordinate and the y-coordinate are positive so their product is positive as is their ratio.

The first quadrant in a Cartesian coordinate system is positive because both the x-coordinate and the y-coordinate of points in this quadrant are positive. This convention is established to simplify mathematical operations and maintain consistency in graphing and analysis.

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.
