    Compute the value of the function.
    
    Specified by:
    
    value in interface UnivariateFunction
    
    Parameters:
    
    x - Point at which the function value should be computed.
    
    Returns:

    UnivariateDifferentiableFunction classes compute both the value and the first derivative of the function.
    
    Specified by:
    
    value in interface UnivariateDifferentiableFunction
    
    Parameters:
    
    t - function input value
    
    Returns:
    
    function result
