A harmonic function is one that satisfies Laplace's equation -- a definition cannot be more precise than that.(adsbygoogle = window.adsbygoogle || []).push({});

However, in the study of vibrations, sine and cosine are considered harmonic functions; but they don't solve Laplace's equation.

And then there are words like: harmonics (for higher frequencies) or "harmonic oscillators" that repeat their motion.

Could someone provide a suite of definitions of the word harmonic?

At the moment, I am confused and thinking that the functions that solve Laplace are related to harmonic oscillators. Am I dealing with multiple definitions?
