Madhava of Sangamagrama, also known as Madhavacharya, is widely regarded as the father of Indian calculus due to his pioneering work in the 14th century.

Madhava of Sangamagrama developed the Madhava Series, also known as the Taylor-Maclaurin Series, which is a method for approximating functions using an infinite sum of terms.

Madhava of Sangamagrama is credited with discovering the concept of the derivative, which is a fundamental concept in calculus used to measure the rate of change of a function.

Bhaskara II developed the Bhaskara Series, which is a method for approximating functions using an infinite sum of terms.
