The basics of linearity

$ e^{(2jt)} $ --->[system]--->$ te^{(-2jt)} $

$ e^{(-2jt)} $ --->[system]--->$ te^{(2jt)} $

$ ae^{(2jt)} $ --->[system]--->$ ate^{(-2jt)} $

$ be^{(-2jt)} $ --->[system]--->$ bte^{(-2jt)} $

$ \cos x = \mathrm{Re}\{e^{ix}\} ={e^{ix} + e^{-ix} \over 2} $

$ \cos 2t = \mathrm{Re}\{e^{jt}\} ={e^{2jt} + e^{-2jt} \over 2} $

Abstract algebra continues the conceptual developments of linear algebra, on an even grander scale.
