Respuesta :

With each iteration, you're swapping the two coordinates, and then change sign of the first one:

First transformation

  • Start with (3,1)
  • Swap coordinates: (1,3)
  • Change sign of the first coordinate: (-1,3)

Second transformation

  • Start with (-1,3)
  • Swap coordinates: (3,-1)
  • Change sign of the first coordinate: (-3,-1)

Third transformation

  • Start with (-3,-1)
  • Swap coordinates: (-1,-3)
  • Change sign of the first coordinate: (1,-3)
