SHM and Damped SHM

Here we have

• how we solve equations like 1) $\ddot{x}=ax$, 2) $\ddot{x}+2\gamma \dot{x}+ax=0$
• Simple Harmonic Motion (although it’s just a mere statement cause everything is in the equation $\ddot{x}+w^{2}x=0$ $\leftarrow$ from Newton’s law $w^2=k/m$)
• Damped SHM and its 3 cases.
