What were the precession of the equinoxes thought to be a result of?

Answer 1

Equinoxial precession is the result of the precession of the Earth's polar axis, with period 260 centuries, nearly

Every year, the equinox time and location are slightly shifted because the poles trace perturbed circles parallel to the Earth's orbital plane (ecliptic), taking approximately 260 centuries to complete.

The longitudinal increment, for each of the two equinoxial locations on the equator, is nearly #360/26000=0.014^o#/ year.

This year, on March 20 and September 23, the time increment is (24 X 3600)/26000=3.32"/year.

The precession of the solstices, which fall on June 20 and December 21 of this year, on the Tropic of Cancer and Capricorn, respectively, is subject to the same increments.

The precession of the equinoxes is thought to be a result of the gravitational forces exerted by the Sun and the Moon on the Earth's equatorial bulge.

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.
