The mathematical path to the sine series before Taylor expansions
In short: Before the modern Taylor expansion became a standard tool, Isaac Newton navigated complex infinite sums and binomial theorems to uncover the properties of trigonometric functions.
This video explores the historical progression of calculus and analysis, specifically focusing on how Newton approached the sine series. It contextualizes these discoveries alongside other foundational mathematical milestones, such as the Binomial Theorem and the Basel Problem.
The content connects these concepts to broader themes in mathematics, including Euler's work linking infinity to Pi, the contributions of Ramanujan, and geometric principles like the area of a circle. It aims to provide a deeper understanding of how these infinite sums were first conceptualized for high-level exams and advanced geometry.
