- Method Detail
  - getFreeParameters
```
int getFreeParameters()
```
    Get the number of free parameters.
    
    Returns:
    
    number of free parameters
  - getOrder
```
int getOrder()
```
    Get the derivation order.
    
    Returns:
    
    derivation order
  - getValue
```
S getValue()
```
    Get the value part of the function.
    
    Returns:
    
    value part of the value of the function
  - getPartialDerivative
```
S getPartialDerivative(int... orders)
                throws MathIllegalArgumentException
```
    Get a partial derivative.
    
    Parameters:
    
    orders - derivation orders with respect to each variable (if all orders are 0, the value is returned)
    
    Returns:
    
    partial derivative
    
    Throws:
    
    MathIllegalArgumentException - if the numbers of variables does not match the instance
    
    MathIllegalArgumentException - if sum of derivation orders is larger than the instance limits
