The Calculus StoryFri 01 January 2021 by Thejaswi Puthraya
"The Calculus Story: A Mathematical Adventure" by David Acheson is a gentle introduction to Calculus. It is light on formulae and mathematics as it's intended audience is supposed to be beginners who wish to get into calculus.
It starts with a brief history of the feud between Newton and Leibniz on who the inventor of calculus is and then gets into explaining the various concepts like differentiation, integration etc through some real world problems.
This is a small book, one that can be finished quickly and is pleasurable.
