To append to an existing notebook list = RandomWord[5] (* Open existing notebook *) X2382901 = NotebookOpen[FileNameJoin[{Directory[], "X2382901.nb"}], Visible -> False]; (* Move selection point to end of notebook *) ...
In converting an Annuity to a Cashflow, I believe the initial payment is being handled incorrectly. Here is code that demonstrates that: (* Annuity with an initial payment and then 5 payments *) (* Present value *) ...
What David Park writes is totally sensible: the built-in Mathematica syntax for graphics has definite limitations, especially for the newbie (and sometimes for the expert, too). As to his example with the disappearing `Tex`t given in the `Epilog`...
I forgot to mention that there was also Macsyma (Lisp based) which at the time (1980's) was the dominant software in the space. Macsyma apparently had several problems, no implementation on various popular platforms, licensing, cost and ability in...
If you want to append a list to another list you could also use the "Join" function: Join[{a,b},{c,d}] = {a,b,c,d}

@NeilSinger This will get looked at in an upcoming review of documentation for `Dot` and perhaps related linear algebra functions. I am optimistic that your suggestions will be seriously considered (read: no promises, but several of us think they...
My document "LPFilter2021.pdf" also designs a Sallen-Key low-pass filter with Fc = 50kHz. It is the 1st example in Ch 2, bump filter. My design approach is much different from the the one presented here. See https://bumpfilter.webador.com or download...
In the contest of this post, I may want to point to this here [Installing Mathematica under 64-bit Kali Linux on a Raspberry Pi][1] First it lists stumbling blocks that may also arise in different contexts (a user must be member of the `video`...
Very clever and useful hack. Thank you for the code.
