Best ResponseYou've already chosen the best response.0Also, teachers can keep the children engaged using topics such as complex numbers that don't even have reallife applications.

Best ResponseYou've already chosen the best response.0True I have seen just a little bit of complex numbers in my intro courses for physics in the subject of circuits but not enough to tell if that is something that I will face in real life.

Best ResponseYou've already chosen the best response.0Well, we use circuits in real life, so...

Best ResponseYou've already chosen the best response.0hahaha also true but I think we use digital circuits which is different from analog and that's where I've seen complex numbers

Best ResponseYou've already chosen the best response.1Complex numbers are used when considering solutions to problems that are modeled by certain differential equations which have a "rotation" in their solution. Example  the stability of predator / prey models of populations. Long story short, they are used in mathematical modeling all the time.
