Simple task:
  • Hide the blue boxes, show the yellows.
  • Add complex numbers of your choice in the yellow input boxes.
  • Calculate the missing complex numbers in the blues (they are the sum of the yellow pair they are between)
  • Check your answers by showing the blues.
(Show/hide numbers with the tick boxes) Harder task:
  • Hide the yellows, show the blues.
  • Click on 'Do Reverse' in the top left.
  • Enter complex numbers of your choice in the blue input boxes.
  • Calculate the missing complex numbers in the yellows.
  • Check your answers by showing the yellows.
What combinations of blues and yellows can be visible in order to fully determine all the other missing values? [Applet uses CAS to solve the reverse simultaneous equations, and is occasionally unstable... working on this!]
