Long before Newton and Leibniz, 14th-century mathematician Madhava of Sangamagrama and the Kerala School of mathematics discovered infinite series for sine, cosine, and pi.

In Hindu tradition, astronomy and math fall under Jyotisha, one of the six Vedangas. Madhava and his successors were Hindu scholars trained within the traditional Gurukula system. Math treatises of the era, such as the Yuktibhāṣā or Tantrasangraha, often opened with invocations to Hindu deities (such as Ganesha or Vishnu). In Indian intellectual tradition, uncovering the geometric and astronomical order of the cosmos was viewed as an act of understanding the divine structure of creation.
