Question

Why we use integration of sin cosine and tringulor signal?

Answer 1

heya mate here is your answer
Integrating a sine wave function is indeed easy, but things gets a lot complicated when it comes to other waveforms. Here follow the equations I'm using to display the waveforms:
Sawtooth wave:
f (x) = mod (f c x, 1.0);
Square wave:
f (x) = sign(cos( f cx ));
Triangle wave:
f (x) = 1
f c | mod (x, f c) − 1
2 f c |
