Problem:

I'm looking for a catch-all function that I can use to calculate the tangent of any polynomial function at x. I'm indifferent to the language used although JavaScript or Python would be prefered! I should be able to pass in any x value and an array of coefficients in the format, a + bx + cx^2 + dx^3 ... and so on.

Example function format:

I'm trying to figure out how to parse S-expressions in C on my own, in order to store data and code for my own rudimentary Lisp (written as a learning exercise, not for production).

Before explaining my code and my reasoning, I should explain that all I know about S-expressions is the introductory section of the Wikipedia article on it, and the occasional glance at Common Lisp code, so the naming of my structs and variables may be a bit off.

My language of implementation is C, and before I defined any functions I created the following structs:

This is a continuation of my questions:

Declaring a functional recursive sequence in Matlab

Is there a more efficient way of nesting logarithms?

Nesting a specific recursion in Pari-GP

But I'll keep this question self contained. I have made a coding project for myself; which is to program a working simple calculator for a tetration function I've constructed. This tetration function is holomorphic, and stated not to be Kneser's solution (as to all the jargon, ignore); long story short, I need to run the numbers; to win over the nay-sayers.

As to this, I have to use Pari-GP; as this is a fantastic language for handling large numbers and algebraic expressions. As we are dealing with tetration (think numbers of the order e^e^e^e^e^e); this language is, of the few that exist, the best for such affairs. It is the favourite when doing iterated exponential computations.

Now, the trouble I am facing is odd. It is not so much that my code doesn't work; it's that it's overflowing because it should over flow (think, we're getting inputs like e^e^e^e^e^e; and no computer can handle it properly). I'll post the first batch of code, before I dive deeper.

The following code works perfectly; and does everything I want. The trouble is with the next batch of code. This produces all the numbers I want.

I am making a GUI in Tkinter and the code prints some attributes of a class. However, something makes it print the attributes from the current instance but also from the previous ones (sorry if the jargon is wrong, I'm really new to this).

So in the Todo-list GUI I have created, I will enter a task and specify some attributes, then print all the attributes. The task name is then displayed in a listbox and all the attributes of the task should be printed to terminal at the same time - however, this is where it will print the current attributes which I have just entered but also the attributes from the previously added task.

This is the code and the print command is in the def show_task(): function.

I am new in R and coding world, pardon if i perhaps mispelled some or more jargon here (cmiiw).

I am facing a challenge to clean city name in a dataframe.

Tried to use GetCloseMatches, strdist_inner_join (with fuzzywuzzy i believe) with dplyr style but still haven't meet my needs.

1st attempt:

I suspect there is some way to use an element’s transformation matrix to calculate its coordinates after being transformed, but I don’t know how to do so.

An example diagram explains this best:

I’m afraid I didn’t take the math route into programming. I can sort-of follow the surface-level details of what a transformation matrix is doing, but my understanding is sort of like being able to read music one note at a time, and only very slowly; I don’t really understand the tune at a higher level, so I don’t really understand the sound of a complete musical phrase—let alone the melody.

Similarly, I don’t understand how transformation matrices work. I have tried searching for explanations to grok transformation matrices, but everything I find is loaded with more math jargon I don’t understand. I just know that they work sort of like a function, and that they are incredibly flexible tools, but that’s it.

Of all the methods available to SVGMatrix (supposedly deprecated in favor of DOMMatrix, but Firefox Dev. ed. is still using SVGMatrix), I have no idea whether .inverse() or .multiply() is what I want, and no idea how to coax a simple set of x and y coordinates out of that matrix.

Note:

• I am not interested in translating screen-to-SVG coordinates here.
• I am only concerned with SVG (user-space) coordinates.

I don't understand what clarification is needed. Please explain your concerns. From my viewpoint, I have asked a question which conforms to the technical area being addressed, I have explained my confusion, I have given an example which illustrates my issues, and I have elaborated on the diagnostic messages received. The respondents to this question understood my question, the example, and the diagnostic messages in sufficient detail that they were able to respond appropriately and to correct my errors and misconceptions. In what way can this dialog be made more pungent with an appropriately asked question?

@Ruzihm stated that there were no lists, I suppose in my example. I would like to explain why that statement is erroneous. Years ago there was a LIFO stack and a FIFO stack. We call a LIFO stack a 'stack', and a FIFO stack a 'queue'. In England, the line standing before, e.g., a theater box office is a queue, and the pigtails that Chinese men wore after the Mongol conquest of China is also a queue. It all depends on context.

The complaint that there are no 'lists' probably extends from the notion that there are no instantiations of objects. But such objects are more appropriately called a linked list, a linked list of linked lists is known as a graph, see e.g. Gnu gSlip documentation. Clearly linked lists were not involved.

In C/C++ it is possible to form a multiple-dimensional array which are non-rectangular. Such objects have historically been known as a 'list of lists', and not an 'array of arrays'. The reason is clear, a 'list' is an object containing items, in programmatic terms, accessible by an index, as in list[index]. This is not to say that a linked list, a.k.a., , is not also a 'list', but normal convention makes more explicit that a is a linked list.

If the question is changed to 'array of arrays', then the examples make little sense. In terms likened to using , there are no 's. So whatever criticism exists for using 'list of lists' is retained and relevant in using 'array of arrays'. If one is inappropriate, the other is also.

The answer given, i.e., use a vector of vectors, is to the point, accurate, and responds correctly to the question about a list of lists. As stated in documentation concerning vectors, for example on https://cpluscplus.com, a vector is a list where elements are accessible by index. In this context, a vector of vectors is a particular list of lists, more particularly, a list of lists which are jagged and not an array of arrays which must be rectangular.

I believe any statement saying that the example posted to explain my quandry in forming a list of lists is inappropriate shows some misunderstanding of software practice and jargon. The question is correctly formed and the examples correctly address the question.

If this question is deleted, or in other ways made non-accessible, then you support an ill-formed statement concerning the question. I hope that this is not done.

I’m having some trouble figuring out the kind of support for Linux that the SQL Server 2019 job scheduler has. It’s clear that the job scheduling procedure API, and SQL Server Agent have both been ported to Linux and appear to work. But there are a limited number of kinds of job steps supported. These “kinds” of job steps are known as “subsystems” in MS jargon. So when you define a job step, you have to specify what type of task it is.

As documented by Microsoft, these subsystems are not supported by the Linux port of SQL Server 2019: CmdExec, PowerShell, Replication Distributor, Snapshot, Merge, Queue Reader, SSIS, SSAS, SSRS.

So that’s clear enough, but then what are the supported subsystems? There are lots of examples of T-SQL steps that can be defined for a job, but are there others? In particular, can I call out to the OS to run an artbitrary shell script? Is there a definitive list of subsystem types that are supported?

So here is the problem. I'm trying to read the data stored on my work access card using android NFC. I have been able to successfully read the data into data type ByteArray, but when I try to convert this value into a string using Sting(byteArray, UTF-8) i get jargons like this 5�〕CG!�昕�>�.

I have tried several encoding charsets but all to no avail. So my guess is the data stored on these access cards are not string value, but if not, what kind of data can be stored there and how specifically can I get to read it successfully. All I need I believe should be stored is just my name or staff ID
