Generally the oscillation terms will tend to be sinusoidal (sin and cos terms), and the exponential terms will be something like a e^(-bt) for the amplitude,...
The sine and cosine functions can also be expressed as complex functions of e. sin(x)= (e^(ix)-e^(-ix))/2i cos(x)= (e^(ix)+e^(-ix))/2 -- No virus found in...
