Second-Order Linear Differential Equations
Summary
We cover finding general solution of second-order linear differential equations which are of the form
$$ \frac{\mathrm{d}^{2} x}{\mathrm{~d} t^{2}}+p(t) \frac{\mathrm{d} x}{\mathrm{~d} t}+q(t) x=f(t). $$The notion of linear independence is also introduced.
