Which mechanism enabled medieval Islamic astronomers to accurately predict lunar eclipses after refining Ptolemy's geocentric model?

💡 Explanation

Astronomers enhanced the prediction of lunar eclipses by developing trigonometric ratios because they allowed calculations of celestial positions with improved accuracy, enabling the determination of eclipse timing. Therefore accurate eclipse calculations resulted, rather than relying solely on epicycles or telescopic observations which lacked precise mathematical frameworks.
