I won't confess to a "whim" but anything from 31 and on seems to provide a smooth enough prediction (a prediction much smoother than the observed data). Also using an odd number gets one the appropriate associated time (the middle of the time...
Hi Jeff. Thank you so much for your swift answer! Best, Per PS It is not on purpose, that my name is "Updating Name" and neither that my profile pic is missing. Must be something wrong with my community profile...
While browsing through the [FunctionRepository](https://resources.wolframcloud.com/FunctionRepository/) I came across [PositionedCases](https://resources.wolframcloud.com/FunctionRepository/resources/PositionedCases) which used a Pattern for...

Thank you so much for your help. I will try my best to use your given link (although I have never used wolfram before). I am using the WOLFRAM alpha and trying to do this.
Murat, you are referring to the subject of Numerical Analysis as "Optimized Simulation". In my opinion this is an equivocation.
m is a parameter of the expression. Whether it is integer or real has no impact on the solution. The sum looks familiar from decades ago. I've no recollection though of where it arises.
Thank you, by "hover help" I was referring to the widget that pops up in Mathematica when you hover with the mouse over a built-in name.
Two ways to do it "with one line" (there are more ways btw) In[901]:= Map[{#^2 Cos[#], Cos[#] Sin[#]} &, {1, 2}] Out[901]= {{Cos[1], Cos[1] Sin[1]}, {4 Cos[2], Cos[2] Sin[2]}} In[893]:= f[x_] := {x^2 Cos[x], Cos[x]...
Thanks!!! It works!
