===== Linearization representation =====
==== Theorem ====
| $X,Y$ ... Banach spaces with topology |
| $f\in C(X,Y)$ |

| @#55EE55: postulate   | @#55EE55: $ f(x+y) = f(x) + \int_0^1\ Df(x+t\ y)\cdot y\ \mathrm d t $ |

==== Discussion ====
^ $ f(x) = f(0) + \int_0^1\ Df(t\ x)\cdot x\ \mathrm d t $ ^
