The drawing shows a snapshot of a transverse wave traveling along a string at 7.9 m/s. The equation for the wave is y(x, t) = A cos (wt + kx).<br />

<br />
A = 2<br />
w = 1240.9<br />
k = 157.08<br />
At what times could this snapshot have been taken? (Give the three smallest nonnegative possibilities in order.)<br />
<br />
I was advised to use the equation V = wavelength / period, to solve for the period.<br />
Then solve for the initial time using pi / 2w.<br />
Then add the period to each successive time. <br />
This is not giving me the right answer. Advice!!!<br />
Then add the<br />
