This Is The Calculus They Won't Teach You

Certainly! In the given text, the author discusses the development of calculus and the contributions of mathematicians such as Christian Huygens, Isaac Newton, and Gottfried Leibniz. They highlight how Leibniz popularized calculus and introduced the notation for differentials (dy/dx), while Newton approached calculus using flexions and treated variables as changing with time. Both Leibniz and Newton used infinitesimals in their calculus, although it was not considered rigorous at the time. The author also mentions the importance of relationships between ideas and people in the development of calculus. Additionally, they briefly mention infinite series and the concept of limits in mathematics.
