Function of x

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

	Input
Function f	f(x) = 3x3 - x2
Function g	g(x) = tan(f (x))
nameless Function	sin(3x) + tan(x)

All internal functions (like sin, cos, tan, etc.) are described in the section about arithmetic operations (4.2.6).

There are commands to get the integral () and derivatives (4.3.11) of a function. You can also use f'(x), f''(x), f''(x), ...for the derivatives of a previously defined function f(x):

f(x) = 3x³ - x²

g(x) = cos(f'(x + 2))

Furthmore, functions can be translated by a vector (4.3.15) and a free function can be moved with the mouse.

Limit Function to Interval

In order to limit a function to an interval [a, b], please use the command Function (see 4.3.11).
