Note: Can always translate IVP to move initial value to the origin and translate back after solving: Hence for simplicity in section 2.8, we will assume initial value is at the origin: y′ = f (t;y), y(0) = 0. Thm 2.4.2: Suppose the functions
Picard's Method of Successive Approximations – GeoGebra
www.geogebra.org › m › jtnkbu72The proof of this statement hinges on the so-called Picard's Method of Successive Approximations. Picard's Method generates a sequence of increasingly accurate algebraic approximations of the specific exact solution of the first order differential equation with initial value. The sequence is called Picard's Sequence of Approximate Solutions, and it can be shown that it converges to exactly one function, , of the independent variable.
