Question:

The following set of differential equations can be used to represent that behavior of a simple spring-mass system, with \(x_{1}(t)\) the mass's position and \(x_{2}(t)\) its velocity:

\(\frac{d x_{1}}{d t}=x_{2}\)

\(\frac{d x_{2}}{d t}=-x_{1}\)

For the initial condition of \(x_{1}(0)=1.0, x_{2}(0)=0\), and a step size 0.1 seconds, determine the values \(x_{1}(0.3)\) and \(x_{2}(0.3)\) using

(a) Euler's method,

(b) the modified Euler's method.
