Hi everyone. I'm bit puzzled about how mathematica deals with Gamma(x) The definition is Gamma(x)=(x-1)! But when I plot, say,
Gamma(x)-(x-1)Gamma(x-1)
it gives me graphs with positive values but it should be zero.. does anyone know what is going on? Many thanks!
Proper syntax would tell you it does equal 0:
Plot[Gamma[x] - (x - 1) Gamma[x - 1], {x, 0, 10}, PlotRange -> {-5, 5}]
