SawtoothWave

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.

Examples

Plot a basic sawtooth wave:

Plot[SawtoothWave[x], {x, 0, 3}]

Sawtooth wave with custom range:

Plot[SawtoothWave[{-1, 1}, x], {x, 0, 3}]
