class ROOT::Math::RotationY


      Rotation class representing a 3D rotation about the Y axis by the angle of rotation.
      For efficiency reason, in addition to the the angle, the sine and cosine of the angle are held

RotationY()

 ========== Constructors and Assignment =====================

      Default constructor (identity rotation)

{ }

explicit RotationY( Scalar angle )

      Construct from an angle

void SetAngle(ROOT::Math::RotationY::Scalar angle)

 ======== Components ==============

      Set given the angle.

void GetAngle(ROOT::Math::RotationY::Scalar& angle) const

      Get the angle

{ angle = atan2 (fSin,fCos); }

Scalar Angle()

      Angle of rotation

{ return atan2 (fSin,fCos); }

Scalar SinAngle()

      Sine or Cosine of the rotation angle

{ return fSin; }

AVector operator*(const AVector & v)

      Overload operator * for rotation on a vector

void Invert()

      Invert a rotation in place

{ fAngle = -fAngle; fSin = -fSin; }

RotationY Inverse()

      Return inverse of  a rotation

{ RotationY t(*this); t.Invert(); return t; }
