Answer 2

The diameter of Earth's orbit around the Sun serves as the baseline for the parallax technique, which measures the apparent shift in a star's position as seen from Earth at different times of the year. Astronomers can use trigonometry to calculate the distance to the star by measuring the angular shift and knowing the baseline.

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.
