(Guitar player and programmer here, don't know much about math. So go easy ;) ).
I recently learned that an audio sine wave is called that way because it is of the shape of the graph of a sine function.
So (correct me if I'm wrong), the equation for a sine function is:
$$p = \sin(t)$$
Where: $p$ is the point on the graph, and $t$ is the point in time. Writing this in Wolfram Alpha indeed shows the expected graph.
So my question: why does the Wikipedia article show much more complex formulas? If Wolfram Alpha says that the formula I wrote above is correct, why all the weird stuff in Wikipedia? The Wikipedia article doesn't show the formula $f(t) = \sin(t)$ even once. What am I missing?
