${\frac {d}{dx}}2x$ derivatives are easy

My derivative

$\int x^{x}dx$ integrals are painful

My antiderivative

$e^{x}=\sum _{n=0}^{\infty }{\frac {x^{n}}{n!}}$

${\text{sin}}(x)=\sum _{n=0}^{\infty }(-1)^{n}*{\frac {x^{2n+1}}{(2n+1)!}}$

${\text{cos}}(x)=\sum _{n=0}^{\infty }(-1)^{n}*{\frac {x^{2n}}{2n!}}$

$n{\text{!}}\approx {\sqrt {2*\pi *{\frac {x^{2x+1}}{e^{2x}}}}}$
