Question

What is the equation

Answer 1

`y = \sin( (2\pi)/(3) x)`

Explanation:

The equation of a sine function is y = a sin(bx), where a = amplitude (aka height) and b equals period (aka time). I'm assuming there isn't any information other than the graph shown, so let's assume that our amplitude is 1 and our period is 2pi/3. Plugging these values into the equation, we get:

`y = (1) \sin(( (2\pi)/(3))x ) = \sin(\frac{2{\pi} }{3}x )`
