# String Worldsheet Area

**Classical Mechanics**Level pending

Consider a relativistic string lying on the y-axis at time \(\tau = 0\), stretching from \(y=0\) to \(y=1\). The string is parameterized so that one endpoint is at \(\sigma=0\) and the other is at \(\sigma=1\), and so that \(\tau = t\). Now allow the string to propagate from time \(\tau = 0\) to time \(\tau = 1\), leaving the string fixed on the y-axis. Find the area of the resulting string worldsheet.
