This homework assignment explores numerical ODE solvers; it is intended for people with some programming ability.

(The following questions are refered to in the solutions video as Part A and Part B of Question 1.)

Write a forward Euler (also called explicit Euler) solver for the simple harmonic oscillator ODEs with , , and

- that is, no friction. Check your solver using the Unit 3.5 quiz solution: start from initial condition:

with timestep to find and compare it to the quiz solution.
