Possible: Inverse trigonometric functions have limited domains. For arcsine and arccosine it is between -1 and 1.

When dealing with trigonometric functions and their inverses one has to make sure the angle unit is chosen accordingly.
I am including a few screen capture to help you do the graph.
First, in Home screen Run the NewProb command to reset the calculator and ready it as a clean slate.
Set the correct angle unit. By default, after the NewProb command the angle unit is reset to Radian. If you want something else change it. See picture. Select 1:radian or 2:Degree.
I will use Radian first.
Press the key sequence that opens the Y= editor. Enter Y1=sin(X)
Remember after a newProb command unit is Radian, Window is standard.
Here is what you get.
Here are the window dimension that gave this picture
Now I am going to change the angle unit to degree and redraw a better framed graph. (I could have done it with the radian unit too.)
As you can see I played with the window dimensions (Xmin=-3*180=-540 and Xmax=3*180=540. The Xscale factor was set to 90 and the range of y-values was reduced to -1.2 to 1.2)
Here is what you get
Before hitting the Graph sequence make sure that the function to be drawn has a check mark to its left (see the 3rd screen capture from the top).

The angle unit is not conform to your problem.
If angle unit in your problem is degrees, change angle unit to degrees on calculator.
Then change the Xmin, Xmax values to about -180 and 180
