1. Any monotonic function is both quasiconvex and quasiconcave.

2. the braking force varies proportionally as the action on the control (monotonic function);

3. The braking force varies proportionally as the action on the control (monotonic function);

4. - the braking force acts in the same direction as the action on the control (monotonic function),

5. the braking force varies proportionally to the action on the control (monotonic function); and

6. The braking force varies proportionally as the action on the control (monotonic function); and

7. the braking force varies proportionally as the action on the control (monotonic function); and

8. It assesses how well the relationship between two variables can be described using a monotonic function.

9. the braking force acts in the same direction as the action on the control (monotonic function

10. 1.3.2. the braking force acts in the same direction as the action on the control (monotonic function),

11. (b) the braking force acts in the same direction as the action on the control device (monotonic function);

12. The paper gives the definitions of monotonic function, bounded variation function and absolute continuous function, and discusses the relationship of the three.
