Review the basic features of sinusoidal functions: midline, amplitude, and period.
David defines the terms amplitude and period for simple harmonic motion and shows how to find them on a graph.

What would the amplitude be? That's easy, it's still three. The wave never gets any higher than three, never gets any lower than negative three, so our amplitude is still three meters. And since at x equals.
Is there a relationship that links the amplitude of the pendulum, theta (in radians), to the percentage difference in the period of a pendulum due to small-angle approximation?
You don't need to. You can just look at the equation and see the amplitude and period from there. Like if you have y=3sin (πx), you can see that the amplitude is 3, and you can just divide 2pi by pi to see.
Sal introduces the main features of sinusoidal functions: midline, amplitude, & period. He shows how these can be found from a sinusoidal function's graph.
