Leonhard Euler (1707-1783) was one of those incredibly brilliant mathematical minds who came up with all sorts of cool math stuff during his lifetime. Lucky for us, one of the things he is credited with is a process known as Euler’s Method for approximating the value of a function at a certain point when only the differential equation of that function is known.
