Question

In Physics class, llan noticed the pattern shown in the accompanying diagram on anoscilloscope. Write the equation that best describes the pattern shown on this oscilloscope.

Answer 1

The general equation of sin function with amplitude A and time period T is,

`y=A\sin ((2\pi)/(T)x)`

The sine equation for A = 5 and T = pi is,

`\begin{gathered} y=5\sin ((2\pi)/(\pi)x) \\ =5\sin (2x) \end{gathered}`

Plot the equation on the graph.
