Solve the differential equation subject to y(0)=2. An Euler approximation to y(x)=2. An Euler approximation to y(x) is given by setting h=x/h, solving the difference equation:

See attached file for equations and full problems.

With initial condition y0=2. The approximation is then y(x)=yn, and show that if n is large, this approximates y(x).
