public double mag () Returns the magnitude of this vector. Returns: the magnitude of this vector. public static Vector2 subtract (Vector2 a, Vector2 b) Returns a new Vector2D equal to a b. Parameters: a vector la b – another vector Returns: la new Vector2D equal to a – b public static Vector2 dirvector (double theta) Returns the vector having magnitude one pointing in the direction theta degrees from the x axis. The components of the vector are equal to (Math.cos (rad), Math.sin(rad)) where rad is theta expressed in radians. Parameters: theta – the direction that the vector is pointing in measured in degrees from the x axis Returns: the unit vector pointing in the given direction Show transcribed image text public double mag () Returns the magnitude of this vector.
