    If you sketch the graph of y = 2 sin(x), you should be able to see at a glance the range of this function. Your x values are in degrees, which you should state.

    Do you know what the graph of y = sin(x) looks like? The graph of your function is related to this one.

    So try numbers between 0 and 180!
