  1. z = x^3-y^3+y*x^2
  2. z = x^3+y^2
  3. z = x^3+y*x^2
  4. z = cbrt(x^2+y^2)
  5. z = cbrt(x^2-y^2)
  6. z = cbrt(x+y)
  7. z = cbrt(x^2-y)
  8. z = cbrt(x^3+y^3)
  9. z=cbrt(x^3+y)-----------------------------------------------------------------------------------------------------------------
