I have a angle : float 180. I’ve converted it to rad angle * Mathf.DegToRad;

Im trying to get the sin, cos and InvSin. cos is fine -1 but sin is wrong Im getting -8.742278E-08, and inverse is giving me an error. the code is as follows id appreciate any help as i am new to this. Thanks

```
function MatrixOp (theta : float, axis : String){
var op = mO();
print(theta);
//setup
op.angleInRad = theta * Mathf.Deg2Rad;
print("angleInRad " + op.angleInRad);
op.cosQ = Mathf.Cos(op.angleInRad);
print("cos " + op.cosQ);
//returns right answer
op.sinQ = Mathf.Sin(op.angleInRad);
print("sin " + op.sinQ);
//returns wrong answer
op.inverseSinAngle = Mathf.Asin(op.angleInRad);
print("inversSin " + op.inverseSinAngle);
//returns error
}
```
