I can use the "Reply" option when I copy someone's text and it appears. However, when I choose the "Quote" option upon copying, maybe the text gets copied but nothing appears. Can someone tell me how to use the "Quote" option on here? Many thanks.

The tutorial question I am working on is, (a) Attempt We can use mean value theorem since ##(c: \mathbb{R} \rightarrow \mathbb{R}~countinity ) \implies (c: [-d, d] \rightarrow [c(-d), c(d)]~countinity)## Thus ##c: [-d, d] \rightarrow [c(-d), c(d)] ## is differentiable on ##(-d, d)##, then...

https://baransel.dev/post/how-to-install-php8-on-centos/ I've followed tutorials like this w/o avail. Everything works but when at last I do php -v, I see different version of php not 8.x.

This is probably a stupid question, but I have never realised that there's an order things should be done in the chain rule , so for example ## \nabla(\bf{v}.\bf{v})=2\bf{v} (\nabla\cdot \bf{v}) ## and not ## 2 \bf{v} \cdot \nabla \bf{v} ## Is there an obvious way to see / think of this...

Hi PF! I'm going through a backtracking tutorial here. That code runs well for me, and is below: %% LOAD DATA % Read a table of daily adjusted close prices for 2006 DJIA stocks. T = readtable('dowPortfolio.xlsx'); % For readability, use only 15 of the 30 DJI component stocks. assetSymbols =...

Summary:: confused in program. Write a while loop to display each character from a string and if a character is a space, then don’t display it and move to the next character. Use the if condition with the continue statement to jump to the next iteration. If the current character is space...

Hi Guys, I am doing a Maxwell&Icepak simulation according to the Icepak tutorial. But I get different result with the tutorial (seems as upside-down). Could you help raise some advice for this situation? Thanks!

I thought I'd make a new thread for some snippets of more "advanced" LaTeX codes that are not covered by the basic LaTeX tutorial. For example: \enclose{circle}{x} \enclose{circle}{x} A \overset{u}{=} B A \overset{u}{=} B A \overset{u}{ \rightarrow} B A \overset{u}{ \rightarrow } B A...

Every time I want to point a newbie to the latex tutorial I have to hunt it down myself. It would be really nice if there was a link or an icon right on the reply window to use in the post. Or am I missing something?

"How hard can rocket science be anyway?" Kerbal Space Program is a sandbox type computer game that leans heavily on concepts of physics (don't let that scare you though, you don't need a calculator nor a book of equations to play it. It's ultimately very intuitive). Given the physics nature of...

I'm reading the online tutorial "How to Think Like a Computer Scientist", which is a Python tutorial. There is an exercise, which I'm trying to figure out. What happens if you call a function and you don't do anything with the result (i.e., you don't assign it to a variable or use it as part of...

I've emailed the M.A. Math program director about this, but I'm just wondering what exactly this entails - generally speaking of course. Is it like a mini-thesis? Or is it more akin to a research paper? How would I select a topic? Fortunately, I know that my interests are in set theory and analysis.

Here are three $n-1$ primality test I would like to describe in this thread. The first one works for the 60% of the cases, the second is usually used when the first fails and the third if first and second both fails. Pocklington's Test Suppose q divides n - 1 and q > \sqrt{n}-1. If there...

Would anyone here know where I could find some kind of tutorial that goes step by step of how to evaluate functional derivatives? I'm looking over my notes, trying to make sense of this functional derivatives stuff the teacher did in class, and it makes no sense at all. I'm not even in the realm...

Homework Statement I am trying to train a neural network using the following training set: (4,6) (9,10) (1,2) (6,2) So, if I enter input 4, it should give me 6. If I enter 9, output should be 10. If I enter 3.5, it should approximate an output based on the training examples...
