Which application results when al-Battani modified Ptolemy's astronomical model using trigonometric functions?

💡 Explanation

When al-Battani used trigonometric functions, a refined astronomical model allowing more accurate orbital parameter calculations occurred because increased fidelity meant reduced accumulated errors and an improved heliocentric reference representation. Therefore enhanced planetary position prediction resulted, rather than measuring Earth, predicting eclipses or mapping star clusters distances that depend fundamentally on other means.
