How did Nilakantha Somayaji's revisions in Tantrasamgraha improve upon Aryabhata's planetary models for Mercury and Venus?
By introducing heliocentric models that replaced the geocentric system entirely.
By providing a more accurate equation of the centre that better predicted their orbital positions.
By simplifying the models to use fewer mathematical calculations for easier use.
