accessing an angle in function mode

how do you access an angle in the function mode. I have two lines (e and f) or I could use three points (BAC). I want to display the sin of the angle on the screen. I have tried sin() with all the combinations I could think of in the parentheses without success

Aw: accessing an angle in function mode

I attached a file with several examples. You can either use the .angle property of lines, or you can use the arctan2 function to get the angle.

Hope that helps,
