At points of discontinuity a fourier series converges to a value that is the average of its limits on the left and the right unlike the floor ceiling and fractional part functions.
The floor of the floor of x.
The symbols for floor and ceiling are like the square brackets with the top or bottom part missing.
The best strategy is to break up the interval of integration or summation into pieces on which the floor function is constant.
Senate majority leader mitch mcconnell r ky delivered the following remarks today on the senate floor regarding the supreme court vacancy.
0 x.
For y fixed and x a multiple of y the fourier series given converges to y 2 rather than to x mod y 0.
Definite integrals and sums involving the floor function are quite common in problems and applications.
