· To obtain the general solution to the real damped harmonic oscillator equation, we must take the real part of the complex solution. The result can be further simplified depending on whether (omega_0^2 gamma^2) is positive or negative. This leads to underdamped solutions or overdamped solutions, as discussed in the following subsections.
