Range
(Built-in Mathematica Symbol) Range[i_max] generates the list {1, 2, ..., i_max}. Range[i_min, i_max] generates the list {i_min, ..., i_max}. Range[i_min, i_max, di] uses step di.
SawtoothWave[x] gives a sawtooth wave that varies from 0 to 1 with unit period.SawtoothWave[{min, max}, x] gives a sawtooth wave that varies from min to max with unit period.
