The arcsine function, denoted as $\arcsin$, is the inverse of the sine function. It returns the angle whose sine is the given number. The expression $\arcsin \frac { 2 } { 3 }$ asks for the angle whose sine is $\frac { 2 } { 3 }$. Using a calculator or a trigonometric table to find $\arcsin \frac { 2 } { 3 }$ gives a value of approximately 0.73 radians when rounded to two decimal places.
