Alternatively, it can be defined as the function
The function also has the following description using a piecewise definition:
|domain||all real numbers, i.e., all of|
|range|| the closed interval |
absolute maximum value: 1, absolute minimum value: 0
|local maximum values and points of attainment||1, at number of the form|
|local minimum values and points of attainment||0, at all points in intervals of the form , with .|
|first derivative|| |
The function is not differentiable at integer multiples of . At even multiples of , the left hand derivative is 0 and the right hand derivative is 1. At odd multiples of , the left hand derivative is -1 and the right hand derivative is 0.
|second derivative||, except at integer multiples of , where it is undefined.|
|mean value over a period|
