### 4.2.5. Function of x

To enter a function you can use previously defined variables (e.g. numbers, points, vectors) and other functions.

Examples:

· Function f: f(x) = 3 x^3 x^2

· Function g: g(x) = tan(f(x))

· Nameless function: sin(3 x) + tan(x)

All internal functions (e.g. sin, cos, tan) are described in the section about arithmetic operations (see Arithmetic Operations).

In GeoGebra you can also use commands to get the Integral and Derivative of a function.

You can also use the commands f(x) or f(x), in order to get the derivatives of a previously defined function f(x).

Example: At first, define function f as f(x) = 3 x^3 x^2. Then you can type in g(x) = cos(f(x + 2)) in order to get function g.

Furthermore, functions can be translated by a vector (see command Translate) and a free function can be moved with the mouse (see mode Move).
