[[Integration]] works nicely with [[#Summation]] and [[#Constant Multiples]]. #### Integration of a constant For any constant $k$, $\huge \int k\d{x} = C $ #### Summation $\huge \ha { \int \pa{f(x) +g(x)}\d{x} &= \int f(x) \d{x} + g(x) \d{x} \\ } $ #### Constant Multiples $\huge \int kf(x)\d{x} = k \int f(x)\d{x} \iff k \text{ is a constant}$
