Are you saying that you do not know what "radians" are? Do you understand what the condition you stated, " " means?

If you are using a calculator to find arcsin(2/3), do you know how to set the "mode" of your calculator? For example, the calculator that comes with Windows has buttons that give "Degrees", "Radians", and "Grad".
