Trigonometry

Aryabhata gave tables of half chords which are now known as sine tables, along with cosine tables. He used zya for sine, kotizya for cosine, and otkram zya for inverse sine, and also introduced the versine.

Brahmagupta used an interpolation formula to compute values of sines, up to the second order of the Newton-Stirling interpolation formula.
