Extensions

An extension for a function is specified by entering a semicolon, followed by the extension, after the function definition. For example:


f(x)=x^2; A1

will show the graph y=x2 with its first derivative. Supported extensions are described below:
N

The function will be stored but not be drawn. So it can be used like any other user defined or predefined function.

A1

The graph of the derivative of the function will be drawn additionally with the same color but less line width. This extension has no effect on functions defined in parametric form.

A2

The graph of the second derivative of the function will be drawn additionally with the same color but less line width. This extension has no effect on functions defined in parametric form.

D[a,b]

Sets the domain for which the function will be displayed. For parametric functions, this is the domain that the parameter takes, and only needs to be specified for the x function.

P[a{,b...}]

Give a set of values of a group parameter for which the function should be displayed. For example: f(x,k)=k*x;P[1,2,3] will plot the functions f(x)=x, f(x)=2*x and f(x)=3*x. You can also use functions as the arguments to the P option.
