An elementary function is one of the following:
- The constant function: $\map {f_c} x = c$ where $c \in \R$
- Powers of $x$: $\map f x = x^y$, where $y \in \R$
- Exponentials: $\map f x = e^x$
- Natural logarithms: $\map f x = \ln x$
- Trigonometric functions: $\map f x = \sin x$, $\map f x = \cos x$
- Inverse trigonometric functions: $\map f x = \arcsin x$, $\map f x = \arccos x$
- All functions that are compositions of the above, for example $\map f x = \ln \sin x$, $\map f x = e^{\cos x}$
- All functions obtained by adding, subtracting, multiplying and dividing any of the above types any finite number of times.
