How does stellar parallax support the heliocentric model?
The fact that we observe stellar parallax means that the a Earth is moving.
An effective way to demonstrate that the Earth is in orbit is to look at a star's position over the course of a year and see how it changes before returning to its initial position one year later.
There wouldn't be parallax if the Earth was at the center of the universe.

The observed parallax of stars is consistent with the heliocentric model, where Earth orbits the Sun, causing the apparent shift in stellar positions throughout the year. Stellar parallax provides measurable evidence of the Earth's motion around the Sun. As the Earth orbits the Sun, nearby stars appear to shift their positions relative to more distant stars. This apparent change in position, known as parallax, can be measured and used to calculate the distance to nearby stars.

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.
