Of the two essays written by him, only one survived  Aryabhata (499), . which in the poetic form set out the mathematical details, . necessary for astronomical calculations, are challenges for the formulation and solution of equations, . the square and cube roots, etc., . Much of this work is devoted to astronomy and spherical trigonometry. Also presented are 33 rules of arithmetic, algebra and trigonometry in the plane. Study demonstrated indeterminate equations with infinite fractions.
Aryabhata found a very precise value of 'pi' (3.1416) and introduced into trigonometry function (1  cos x). The scientist surmised that the rotation of the heavens  only apparent and is a consequence of the Earth's rotation around its axis.
