What's the craziest/most interesting concept/idea of math you know of?
l've just discovered you can evaluate real derivative/integrals using complex numbers by converting them to complex numbers to evaluate an easier derivative/integral there and then come back to the 'real world' by taking the real or imaginary part of that result. lt just blew my mind

That's not what Laplace Transforms do

>converting them to complex numbers
You don't convert them, rather you "view" them as complex numbers. For example, the real number sin(x)·e^(b·x) can be viewed as the complex part of e^(x·(b+i))

fractals are pretty nuts in general

Can this be a fractal thread?

l don't understand laplacian transformations yet although l know how to use them. l was thinking more about this: >>8312788
ln this example you easily could take the n-th derivate by continuously deriving e^(x·(b+i)) as (e^(x·(b+i)))_n = (i+b)^n · e^(x·(b+i)) and then taking the imaginary part of it, which is much easier than deriving sin(x)·e^(b·x) alone

lf you think that's cool you're gonna have a heart attack once you study group theory

LT can also be understood as series,
