Indian Mathematicians and Astronomers

Aryabhata was an Indian mathematician and astronomer who lived in the 5th century CE. He is credited with developing the concept of the cosine function, which is a trigonometric function that is used to calculate the length of the side of a triangle.

Aryabhata was an Indian mathematician and astronomer who lived in the 5th century CE. He is credited with developing the concept of the tangent function, which is a trigonometric function that is used to calculate the ratio of the opposite side to the adjacent side of a triangle.
