How Euler Astonished the World with the Amazing Fact e'z=cosz+isinz and Other Amazing Facts On the Journey to It Once upon a time (1748) there was a mathematician named Euler, who at the age of 35 used innite 7 . series to find some amazing facts. The goal of this activity is to show how he arrived at the Amazing , ' 9"? Feet in the title of this activity, but more beautiful gems will be shown along the way. In particular, ' Amazing fact #1 4' l 1 1 1 l The innite series + - + + - + + = e: 2.718281828459045...-' ' 0! 1! 2! 3! 4! . . 1 1 1 ,, fighe series 6;++ +-1- + converges quickly.
