Holy crap. I have no freakin' idea.

[math]e^{a+b} = e^a \cdot e^b[/math] for a start. Furthermore, [math] e^{i\alpha} = \cos \alpha + i \sin \alpha [/math].

What kind of math is this?

complex algebra.. argand diagram...complex trigonometry will cover it pretty much for ya.

 

oh and a^x * a^y = a^(x+y) is just algebra from age 13 or 14 or something.

.atheist gave you the best succint steps really. (normal algebraic rules and euler's formula),

Thanks, probably not going to take complex or abstract algebra until I'm in college.

It's definitely not abstract algebra - that refers to something else entirely.
