The Madhava Series is a group of infinite series developed by the Indian mathematician Madhava of Sangamagrama in the 14th century, which laid the groundwork for calculus and mathematical analysis, particularly in trigonometry. These series include expansions for sine, cosine, and tangent functions, contributing significantly to the development of infinite series and their applications in mathematics.

The Madhava School of Astronomy and Mathematics continued his work, further developing these series and their applications in astronomy and geometry.
Review Questions
How did the Madhava Series influence the development of calculus and the concept of infinite series?
The Madhava Series played a pivotal role in the early development of calculus by providing foundational techniques for working with infinite series. Madhava's methods demonstrated how functions could be approximated using sums of infinitely many terms. This innovative approach set the stage for later mathematicians to formalize calculus concepts, particularly regarding convergence and the use of series to model mathematical phenomena.
Discuss how the trigonometric functions were represented through the Madhava Series and their significance in mathematical analysis.
The Madhava Series provided explicit infinite series representations for trigonometric functions like sine, cosine, and tangent. These representations allowed mathematicians to calculate these functions with increasing accuracy as more terms were included. The significance lies in how these series not only advanced trigonometry but also facilitated further developments in mathematical analysis by linking geometric concepts with algebraic expressions through infinite processes.
Evaluate the long-term impact of Madhava's contributions on both Indian mathematics and its eventual reception in Europe during the Renaissance.
Madhava's contributions had a profound long-term impact on both Indian mathematics and European thought during the Renaissance. His exploration of infinite series established critical foundations for future mathematical inquiry, which were largely overlooked until they resurfaced in Europe. As European mathematicians began to encounter these ideas through translations and interactions with Indian scholars, they recognized their potential for advancing calculus. This cross-cultural exchange ultimately enriched global mathematics and shaped modern analytical methods.
