v2.c34.257.4

यतश्चन्द्रगतिः महत्त्वान् प्रतिक्षणं समा न भवति अतस्तदर्थं अयं विशेषोऽभिहितः;— nothing can be clearer than this conception of ‘momentary’ motion.—Bháskara, Siddhánta-S’iromani, Ganitádhyáya, Gatisphutiprakarana: cf. also प्रतिक्षणं सा न समा महत्त्वतः, ibid., cf. also Goládhyáya, Tátkálikí-karana-vásaná-prakarana, where Bháskara points out that the mode of computing adopted by the A’cháryya (Brahmagupta) is a rough simplification. The computation of relative motion and the idea of resolved components of motion were of course familiar to the astronomers.—(Cf. एवं सत्याचार्येण लाघवाथं इष्टघटीसम्बन्धिन्यो गतिकला अर्क प्रक्षिप्ताः। ibid.) I may add *en passant* that Bhāskara's formula for the computation of a table of Sines also implies his use of the principle of the Differential Calculus.
