-Plot of Chebyshev's <math>\psi</math> function, along with the approximation <math>x-\log 2\pi</math>. This function can be defined in [[Mathematica]] by:
- ψ[n_] := Sum[If[PrimeQ[p], Floor[Log[n]/Log[p]] Log[p], 0], {p, 2, n}]
- SetAttributes[ψ, Listable]
-The above plot was then generated by:
-  Plot[{ψ[n], n - Log[2π]}, {n, 0, 50},
-    AxesLabel -> {n, "ψ(n)"},
-    TextStyle -> {FontFamily -> "Times", FontSize -> 16},
-    PlotStyle -> {{Hue[0.6], Thickness[0.006]}, {RGBColor[0, 0, 0]}}]
