La trigonométrie - Introduction

We offer a historical introduction to trigonometry, from the Plimpton 322 tablet (an archaeological find from 1800 BC) to the concept of a chord introduced by Hipparchus. We explain how Hipparchus used it to calculate the distance from the Earth to the Moon in the 2nd century BC.

And if you'd like to give us a hand in return, feel free to support us on Tipeee: https://www.tipeee.com/clipedia. We'll need your help to cover the entire curriculum in five years!
