The linear approximation of S ( t) around t j at t j + 1 is. S ( t j + 1) = S ( t j) + ( t j + 1 − t j) d S ( t j) d t, which can also be written. S ( t j + 1) = S ( t j) + h F ( t j, S ( t j)). This formula is called the Explicit Euler Formula, and it allows us to compute an approximation for the state at S ( t j + 1) given the state at S ( t j).

19.12.2017 · Euler Method : In mathematics and computational science, the Euler method (also called forward Euler method) is a first-order numerical procedurefor solving ordinary differential equations (ODEs) with a given initial value. Consider a differential equation dy/dx = f (x, y) with initialcondition y (x0)=y0
