Consider the initial value problem for the equation of linear pendulum L.
with a=0.6, b=1.7.
Find (analytically) the phase trajectory of this system passing through the given point (a,b).
Write down the euler method for the system from the first part.
This shows how to work with an initial value problem and write it as a system of first-order equations, write down the Euler method for the system, and find the phase trajectory.
