Note 1 to entry: The value of the function *f* of *n* variables ${x}_{1},\text{\hspace{0.17em}}{x}_{2},\text{\hspace{0.17em}}\dots ,\text{\hspace{0.17em}}{x}_{n}$ is denoted by $f({x}_{1},\text{\hspace{0.17em}}{x}_{2},\text{\hspace{0.17em}}\dots ,\text{\hspace{0.17em}}{x}_{n})$.

Note 2 to entry: In many practical applications in electrotechnology, functions of one variable are used. This variable is often the duration and the function is then called "function of time" and denoted by *f*(*t*). But the variables may also be space variables (e.g. coordinates), frequency, etc.
