Calculates both function values and derivative values of the given function of one variable.
Number of values of the independent variable used in the function calculation.
Default: 10
Formula that defines the function. The formula can contain any number of valid variables.
Entering Valid Variables
This node accepts variables that use the following format rule: variables must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.
Start value of the interval where this node starts calculating values.
Default: 0
End value of the interval where this node stops calculating values.
Default: 1
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Variable values used in the function calculation. The values are equally spaced from start to end.
Function values at the corresponding points in x values.
Derivative values of the function at the points in x values.
Error information.
The node produces this output according to standard error behavior.

This node has no optimal step. To obtain highly accurate values of differentiation, start with the symbolic differentiation by hand, and then use the Evaluate y = f(x) (Optimal Step) node, where f is the derivative of the function.
The following graph shows the function values and the derivative of function f(x) = sin(sinc(x)) in the interval (-20, 20).
