I’m writing a paper on real world applications of complex numbers and can’t understand it at all. If you have any other real world applications, that would be super helpful too. Thanks!

Complex numbers have “two” axes, the “real” number and the “imaginary” number. A number otherwise has one “value” and can be represented [on a line](https://i2.wp.com/mathblog.wpengine.com/wp-content/uploads/2017/03/numberlines-thumbnail.jpeg?resize=573%2C247&ssl=1); complex numbers on the other hand have 2 “axes” and can be represented on a plane. This makes them useful for representing vectors, or things that rotate (cycles), or have periodic behavior, or waves (AC electricity for example).
