Practical Applications of Imaginary Numbers
Date: 11/23/95 at 19:48:3 From: Anonymous Subject: imaginary numbers Dear Dr. Math, I am having difficulty in finding incentives and practical applications for my students when I am required to teach them imaginary numbers. What are the real life applications that would make this lesson more meaningful to students? Thank you for your help. Bill Mitchell

They're really cool, and if you want to be able to understand them, you have to know about imaginaries (although not all that much, really). The other main area I've seen imaginaries come in where you wouldn't really expect them (at first, anyway) is in Alternating Current circuits. You use them to figure out phase shifts and stuff like that. It's pretty neat. I think that the bottom line, though, is that imaginaries are just really cool, and that should be reason enough to learn about them. I mean, it's just so neat to know that i Pi e + 1 = 0.
