History

Within Ptolemaic astronomy, which calculation error resulted when approximating circular orbits to fit observed planetary motion using algebraic methods?

A)Increased equant point eccentricity
B)Introduced epicycle circumference variations
C)Diminished deferent orbital velocity
D)Amplified parallax angle discrepancies

💡 Explanation

Increased equant point eccentricity arose because the algebraic approximations introduced inaccuracies while trying to reconcile circular motion with observed retrograde motion; therefore, eccentricity increased rather than providing correct deferent sizing or related epicycle parameters.
