← HistoryWhich limitation arises when calculating planetary positions using Ptolemaic epicycles and algebra?
A)Perfect circular motion not maintained✓
B)Parallax shifts calculation errors
C)Computational accuracy increases rapidly
D)Elliptical orbital approximations are disallowed
💡 Explanation
Loss of "perfect circles" ensues because equants, introduced algebraically to maintain predictive accuracy, altered uniform circular motion assumptions; therefore, observed non uniform planet speeds deviated, rather than strictly adhering to uniform Aristotelian principles.
