Questão 2549243

\(v\left(t\right)\ =\ 311\ sen\left(120\pi t\ -\frac{\pi}{3}\right)\)

\(v\left(t\right)\ =\ 440\ sen\ \left(60\pi t\ -\ \frac{\pi}{6}\right)\)

\(v\left(t\right)\ =\ 440\ sen\ \left(60\pi t+\frac{\pi}{3}\right)\)

\(v\left(t\right)\ =\ 622\ sen\ \left(120\pi t-\frac{\pi}{3}\right)\)

\(v\left(t\right)=662\ sen\ \left(60\pi t\ +\ \frac{\pi}{6}\right)\)
