Bhaskara I was the first mathematician to define the sine function as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

Bhaskara I's formula for the sine of an angle is $$sin(x) = rac{opposite}{hypotenuse}$$, where x is the angle and opposite and hypotenuse are the lengths of the opposite and hypotenuse sides of the right triangle, respectively.

Bhaskara I's formula for the cosine of an angle is $$cos(x) = rac{adjacent}{hypotenuse}$$, where x is the angle and adjacent and hypotenuse are the lengths of the adjacent and hypotenuse sides of the right triangle, respectively.

Bhaskara I's work on trigonometry was heavily influenced by the work of Aryabhata, another Indian mathematician and astronomer who lived in the 5th century.

Bhaskara I's contributions to trigonometry were later transmitted to the West through the works of Al-Khwarizmi, a Persian mathematician and astronomer who lived in the 9th century.

Bhaskara I's work on trigonometry had a profound impact on the development of astronomy, navigation, and surveying.
