Haskell notes
Easy plotting: plots $\dfrac{\sin x}{x}$ and writes it to the file `filename.png`.
Prelude> import Graphics.Gnuplot.Simple
Prelude> plotFunc [PNG "filename.png"] (linearScale 1000 (-20,20)) (\x -> sin x / x)
Easy integration (even on all $\mathbb{R}$):
import Numeric.Integration.TanhSinh
