Live Notes PDF-beta . Euler's method is an interative algorithm which generates a nite approximation of the solution of a first order differential equation: dy a _ F(t>y) passing through (to, yo). The main idea is to read of the direction along which a curve should proceed at a given point from the differential equation. Then proceed to (251,211) and update the direction by reading of new direction F(t1,y1) from the differential equation. Then repeat the process. 4:24 4 a: C) 4 Safari
