I don't know where this question fits, whether it is the right place...

I plotted the Logistic Function $y=\frac{0.8}{1 + e^{-(x-6)}}$ using wolframalpha, here.

Now I want to make it discrete, so I can copy it to excel and make a plot. I want to split the range, let's say, to 20 elements.

(so one column in Excel holds 20 $x$ values, and another column holds 20 times the "computed" formula, dragged down 20 cells, as is customary in Excel...)

Is there a simple way to do it via wolframalpha, rather than mastering Mathematica now?

  • You're trying to get discrete value of the points? Which x-values do you want? – actinidia Dec 03 '17 at 18:52
  • @Moo This is not a graph of a discrete function. – callculus42 Dec 03 '17 at 18:55
  • @TiwaAina, yes, I want the graph to start from $x=0$ and end where $y=0.8$ (which is basically where $x=10$, so if I can't use the $y$ value, I can suffice with the $x$) – Tar Dec 03 '17 at 19:01

    you can use the command Table[{x,0.8/(1+e^(-(x-6)))},{x,0,10,0.5}] on WA to get a list of 21 pairs of $(x,y)$ (the 4th parameter in 2nd argument is the step). – achille hui Dec 03 '17 at 19:15
  • @achillehui: that's it :-) post an answer so I could accept it. Thanks! – Tar Dec 05 '17 at 08:51
