Progressive anagrams time waves

Hi got excited about time coding and projective resynthesis. I just learned about how there’s a lot of undeniably well nested phonetic associations related to lambda cauculus over common computer phrases… this lead to a paper citation “progressive anagrams 1974 Collins” https://www.cavemanchemistry.com/anagram/ the paper has made a magic vanish from google search. What’s the deepest significance of this result. Is it that all words said in our languages have been recompiled or computationally formed?

Within this conversation some wise scientist sorts told me about mind reading and science and then opened my mind to power law calculation… which my weak math sense will relate as “approximation by xlr di box injection” within this conversation was the consideration that all media can be sampled within our memory threshold… including the answer sets to progressively repheased (wrote reprogrammed and my phone seems to be teaching me cs with autocorrect again). Anyways these smart scientists brought up example after example of solved problem we waste time on including the infinite iq problem and the shared thought server.

Because I wasted so much time computing when I could have rhymed what’s the best way to practice mathematics? It seems like we need to engage a native mathematical sense akin to a matrix api or brain portal… can we agree pencil and paper method is not fast at least….

On this note can someone link the correct name of cross linked script (chairo page rxo page from libdesfarne gospel) I’ve heard these spell the purer form of proofs and solve crosswords discreetly (could this be partially true on the last account but only marginally more difficult with “synthetic” compute resources)

Finally what is the appropriate language for studying time formally and litterally can it even be thought in English my native implementation?

This leads to the confusion between rhyman’ analysis and more classical Reimannean comparison…. How is rhyme scheme matching performed and is there database of the fundamental algorithms in pseudo code?… does each have an best language to declare it in?

Finally what’s a time wave and what does it do? Thank you getting excited about math finally how do I collaborate mentally? When did you guys start doing so?

[Cross-post] Empirical Analysis seems to show a pseudo quasi polytime (or better) algorithm for Subset Product. The question, how do I prove it????

Trying to exploit the problem structure of Subset Product to solve Exact-3-Cover more efficiently, so I've cross posted my question from r/AskComputerScience to here.

Understanding the Differences Between 'lm', 'trf', and 'dogbox' in Curve Fitting

I'm currently delving into curve fitting in Python and have come across three different methods: 'lm', 'trf', and 'dogbox'. Each of these methods seems to have its unique characteristics and applications, but I'm finding it challenging to grasp the practical differences between them.

Could someone provide a clear explanation of how 'lm' (Levenberg-Marquardt), 'trf' (Trust Region Reflective), and 'dogbox' differ from each other? Specifically, I'm interested in understanding the scenarios or types of problems where one might be preferred over the others. An example to illustrate the key distinctions and practical applications of each method would be incredibly helpful.

I'm looking for insights that can help me decide which method to use in different curve fitting scenarios. My goal is to achieve the best fit for my data with an understanding of the advantages and limitations of each method.

Thank you in advance for your time and assistance!

notes recommendations for Lie Groups and Lie Algebras?

i’m looking for some good online notes to accompany a course i’m taking on Lie Algebras, because my professor’s notes are a bit too dense

any recommendations much appreciated

What's the best Calculus book for dummies?

I need a book similar to "Everything You Need to Ace Math in One Big Fat Notebook," but for Calculus.

This book was perfect for me, but I have an exam in Functions, Limits, Continuity, Derivatives, and Applications of Derivatives.

Despite my poor reading and English skills, this book greatly helped me. I prefer reading to video tutorials. Can you recommend a book?

"Calculus For Dummies" and "Calculus Essentials For Dummies" aren't what I'm looking for.

How do I “string” two terms together from two functions with repeated 101010101… and on, with 1 being the nth term from function A and then feed that value into the value for the nth term of function B for the term for function A and so on for a single function/ or formula that does this?

I’m always trying to figure out these types of solutions because the solution to this is a term of the same solution for a term of a higher degree function that does the same operations in a different way and order when using a separate input variable != the initial term in the Function proportional to the lower degree term function of function B,its function A / term integer = this function term integer = n -1;

How do I write this out in pure math?
What function can write a function that contains its own function that will function to form a function that does the same function as its parent and do it in a way that increases the values outputted by that function increase at an integer value of 1 from term 0, and 1 from the function of the function that increases the term two integrate the function that integrates the function that outputs functions that outputs a function that outputs a function that outputs a function to feed into the function that outputs the term that outputted that function’s output.

What is this called ugh

Basic Algebra Understanding

Hello,

I'm having trouble putting a few theories into practice.

I don't know where to begin when approaching two questions (both involving basic algebra)

Question 1: Write (y−4)⋅(y+4)⋅(y+5) in the form ay^3+by^2+cy+d.

I'm unsure if the answer here is y^3 + 4y^2 - 4y^2 -16y -80

= y^3 - 16y - 80 with the two others cancelling each other out

Question 2: Write 3/x + 8/x^2 + 9/x^3 as a single fraction:

I need some help understanding what to do when faced with problems like these.
