   9# Antidifferentiation
  10
  11If $F'(x)=f(x)$, then $\int f(x) \cdot dx = F(x) + c$
  12
  13$$\int x^n \cdot dx = {x^{n+1} \over {n+1}} + c, \quad n \in \mathbb{N} \cup \{0\}$$
  14
  15Rules:
  16
  17$\int [f(x) \pm g(x)] \cdot dx = \int f(x) \cdot dx \pm \int g(x) \cdot dx$  
  18$\int kf(x) \cdot dx = k \int f(x) \cdot dx$, where $k \in \mathbb{R}$
