Mathematica is intensely case sensitive. It understands Tan[z^2] to be a predefined function with the expected properties. It understands tan[z^2] to be a function, but it has not yet seen any definition of that function and so treats that as...
Try PrintFredAndHarry[]:=( Print ["Fred"]; Print [ "harry"] ); which creates a function with no arguments If you evaluate PrintFredAndHarry[] it should print your two words. Without the () the precedence of the ; would be...
Hint: Instead of naming your functions L1[j],S1[j],L2[j],S2[j],... what if you named them L[1,j],S[1,j],L[2,j],S[2,j]... If you did that then could you think of a way of defining L[i,j] and S[i,j] in terms of ...
Perhaps this is because Plot3D does not plot complex functions by default. Try wrapping Re[...] around the expression you want to plot. If that works then you can replace Re with Im and see the imaginary part.
Just as a simple quick experiment, can you scale all your 10^-30 and 10^-76 and 10^-19 up nearer to 10^-2 scale all your 10^51 and 10^73 and 10^56 and 10^27 and 10^5 down nearer to 10^2 include your definition of q[x] possibly eliminate...

It is possible that AssociateTo behaves in a way similar to AppendTo. If that is true then for each new key->value that you add to your association makes a new copy of the the existing key->value pairs and then inserts or updates one new key. That...
I peeked at one of the three using port = {"^GSPC", "GLD", "VCSH"}; ret1 = FinancialData[#, "Return", {2021}] & /@ port; FullForm[ret1[]] and that gives some functions that can be looked up in the help system. It appears...
Is this what you are looking for? tbl=Table[conv,{y,Pi/16,2Pi,Pi/16}]//N If that doesn't produce exactly what you are looking for then please edit your post to show exactly what the result should be and I'll see if I can match that.
Replace If[m>=100 with If[m>=10
