Take a look at some of the examples in the math section, particularly the Sine Wave Example...

thanks, i cant seem to find anything that can make a sine wave remain static

managed to get a static wave that I can adjust, struggling to make it repeat though

What code do you have?
I'm not too experienced in this area...

If you can display one wave, then perhaps simply looping over it is sufficient?

1. for(int i = 0; i < width; i < waveWidth) {
2.   translate(waveWidth, 0);
3.   //Display wave
   
4. }
