Commands may be entered in 2-D math as they are entered in 1-D math. This is called command form, as the command name is typed in full. Here is an example using the int command, using both 1-D and 2-D math input.

Some commands allow alternative forms of entry that use mathematical notation. Many of these forms are available in Maple's palettes. For example, the integral computed above can be entered using the definite integration template from the Expression palette:

${\int }_0^4{x}^2\+\frac{x}{5} \ⅆx$

Additional forms are available through command completion. For example, if you type int and invoke command completion, you will be offered, among other choices, the option to compute the Cauchy principal value:

$\mathrm{PV}{\int }_{-1}^2\frac{1}{x^3} \ⅆx$

Many Maple commands offer options that let you control various aspects of the command's behavior or the form of the output. For example, the int/details help page shows several options for the int command. In general, when using an option, it is necessary to use the command form rather than mathematical notation. You can still use 2-D math notation for the command's arguments. However, the command name must be given explicitly. In the example below, the option 'numeric' causes the command to return a floating-point result.
