← HistoryIf a geared astrolabic quadrant shows irregular motion due to wheel eccentricity, which algebraic model more accurately predicts variance?
A)Elliptic Fourier series addition✓
B)Polynomial trend line subtraction
C)Linear regression data filtering
D)Gaussian error function analysis
💡 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.
