The general solution of the differential equation $y''+\omega^2y=0$ can be written as: $$y=\alpha\cos{(\omega(t-c))}+\beta\sin{(\omega(t-c))}$$ Is it correct to say that:
- $\omega$ and $c$ are constants
- $\alpha$ and $\beta$ are arbitrary constants
- $t$ is a variable
QUESTION: What is the difference between constants, arbitrary constants and variables?
