_{Improved euler's method calculator. Euler's Method is a method for numerically approximating values of a function, given its derivative (dy/dx) and a point (x, y) to begin with. It is especially useful when the derivative expression contains y's that may be otherwise difficult to resolve with integration.. Begin by choosing dx; the smaller the dx, the more accurate the result, but the more numerous the steps. }

_{Use Euler method with N=16,32,...,256; Code of function Euler(f,[t0,T],y0,N) Initial value problem. We consider an initial value problem for a 2nd order ODE: and we want to find the solution y(t) for t in [0,4]. We first have to rewrite this as a 1st order system: Let and , then we obtain.
