Question

What is the period of the sinusoid given by -4sin(2π/(3)x)?

Answer 1

\[2\pi\]
Maybe as it is sin afterall

Answer 2

Looking for the period of the function below ?
\[-4\sin(\frac{2\pi}{3}x) \]

Answer 3

The period of sin(a) is 2*pi in terms of a
in our case a=(2*pi/3)x so the period of sin() in terms of x will be 3
