If a geared astrolabic quadrant shows irregular motion due to wheel eccentricity, which algebraic model more accurately predicts variance?

💡 Explanation

Elliptic Fourier series more accurately models periodic motion irregularities because it decomposes complex waveforms into sums of ellipses, rather than a simple polynomial which models trends. Thus, it is better for correcting erratic quadrant readings; rather than simply discarding data.
