Ballistic time of flight

I have the formula from wikipedia - https://en.wikipedia.org/wiki/Projectile_motion

this is the code:

Code (CSharp):

1. public static float GetTimeOfFlight(float vel, float angle, float height){
2.  
3. //        return ((vel * Mathf.Sin (angle)) + Mathf.Sqrt (Mathf.Sin (angle) * Mathf.Sin (angle) + 2.0f * -Physics.gravity.y * height)) / -Physics.gravity.y;
4.         return (2.0f * vel * Mathf.Sin (angle)) / -Physics.gravity.y;
5.     }

both of these line should return the same result, and they do, but the value i get is jumping between positive and negative, how could this be?

 

I'll tell you how you idiot, you're passing in degrees when it take radians.

UGH!
