 Mar26 awarded Notable Question Feb3 comment How can I convert a complex number a+b I to the exponent form A Exp(I phi)? sorry if I'm wrong because I'm not sure about these terms in English, but isn't this an exponential form, not polar?

Aug18 comment How to modify the elements of a list in a loop? @MichaelE2 I edited the question Aug18 revised How to modify the elements of a list in a loop? deleted 252 characters in body Aug18 comment How to modify the elements of a list in a loop? @MichaelE2 sorry, but I do not understand what I need to state. Doesn't my question state that I need to modify many elements so I need to use a loop for this. It does not matter whether I will get these values via Print[points]; or Print[{item1, item2, item3, item4}]; as in my code. The main problem is to perform a series of modifications on a list of values in a loop in the shortest way Aug18 comment How to modify the elements of a list in a loop? @MichaelE2 if I remove f#, N[#], semicolon and print in order to use the exact version of Alexei's answer, it still does not give the correct result.

The result consists of a list with inner list which contains 36 lists, which I can assume are the results of each matrix apply, that is 12 points of the first matrix product,12 of the second one and 12 of the last. Am I correct? Aug16 asked How to modify the elements of a list in a loop?

Jul29 comment Is it possible to plot a second-order curve by its non-canonical equation? sorry, my question was incorrect to some point. I meant to set axes origin at 0,0, is it possible? Google says nothing Jul29 comment Is it possible to plot a second-order curve by its non-canonical equation? could you suggest how can I draw the x and y axes on this plot, please?
