In this case, we will return different digital sine:
var a=Math.sin(3);
var b=Math.sin(-3);
var c=Math.sin(0);
var d=Math.sin(Math.PI);
var e=Math.sin(Math.PI/2);
var b=Math.sin(-3);
var c=Math.sin(0);
var d=Math.sin(Math.PI);
var e=Math.sin(Math.PI/2);
a, b, c, d, and e output:
0.1411200080598672
-0.1411200080598672
