How do you find the period of a modified sine graph?
- What do you mean? The period is the smallest number a such that
- f(x+a) = f(x) for all x
- i.e. the point at which it starts to repeat itself
- What does your modified sine graph look like?
There is some content at oscillator that needs sorting out. Please read the proposal at Talk:oscillator Cutler 18:51, 18 Feb 2004 (UTC)
The function name f is re-used here, sometimes for an arbitrary function and sometimes for a specific one. Would it be clearer if the function that gives the "fractional part" of its argument were named something else? Frac is a reasonably common name for this operation in programming languages. --FOo 02:57, 9 Dec 2004 (UTC)
