Why stop there? Use the Argand plane and then get all your trigonometric functions for free! Gotta get those young whippersnappers into shape!

Obviously I jest, but boy would it have made things a lot easier if we did them that way! To your point, I feel like we do a lot of the things we do because that's the way we've always done it. Every now and then we need to step back and ask whether that still makes the most sense.
