The greatest integer function and the absolute value function are both examples of piecewise defined functions in mathematics. The greatest integer function maps a real number to the largest preceding integer, while the absolute value function measures the distance from zero. These functions illustrate important concepts in real analysis and behavior of functions. ;
The greatest integer function, denoted as ⌊x⌋, returns the largest integer less than or equal to x, while the absolute value function, |x|, measures the distance of x from zero. Both can be defined using piecewise notation and play a significant role in algebra and real analysis. Their understanding is crucial for advanced mathematical studies.
