public interface Differentiable
extends Derivative

A function that also allows calculating of some of its derivatives. The differentiateAt(int, double) method returns the value of the n-th derivative at the stated value of the independant variable.

Method Detail

getDerivativeOrder

int getDerivativeOrder()

Returns the maximum order of the derivative that can be calculated.

differentiateAt

double differentiateAt(int n,
                       double t)

Calculates the value of the n-th derivative at the value of the independant variable stated. If the function cannot calculate the required order, it is perfectly legal, but not required, to throw a runtime exception.

Parameters:

n - The order of the derivative to be evaluated.

t - The value of the independant variable.

Returns:

The value of the n-th derivateive at t.

Throws:

IllegalArgumentException - If the order requested is higher then the maximal order served.
