I'd love to know your thoughts! Did I miss anything out that you were hoping to see? Did I skip over any bits too quickly? Let me know what you think!

[@momohLBY]

Excellent guide, can't wait for more! Thank you for your time, it has helped immensely.

[@soswriting]

Thank you for saying that! It really does mean a lot to know that they're useful :) the next one is in the final stages of production and on its way soon™

Regarding Schrodinger's equation, the physics usepackage has to useful macros including \pdv{ } which generates partial derivatives and \laplacian which generates the upside-down "triangle" squared. Moreover, often the math equations that you find in Wikipedia have been formatted in LaTeX can therefore simply be copied and drop into the text! It saves a lot of time and you can also modify them afterwards but most of the heavy lifting has been done.

That's a great tip, I wasn't aware of the physics package! Thanks for bringing it to my attention :D

[@mikhailbandurist8652]

Please don't stop! Your tutorials are really good and useful!

[@soswriting]

Thank you very much for saying so! As soon as it's quiet enough to record again, normal production will resume! :)

@@soswriting Thank you!)

[@ManuelJorgeMarques]

Nice one! Looking forward to the next video 😉 (hopefully involving tables!)

[@soswriting]

Thank you so much! Tables are a headache for sure, I don't think anyone would mind if I did them next :)

[@s.h.i2553]

Cool !!! This video is rich in information 👍👍 thank you waiting for other videos😃😃

[@soswriting]

No problem at all! I'm glad you liked it and I hope it helps :)

[@haraldurkarlsson1147]

Most LaTeX experts these days suggest using \( formula \) for inline math code and \[ formula \] for display style math mode (unless of course you use \begin{equation} etc or \begin{align} etc.). For some reason they recommend not using $ $ or $$ $$.

[@haraldurkarlsson1147]

I use a stand-alone package (TeXShop) to run LaTeX on my Mac since I am not a big fan of online apps (what do you do if the internet does not work or is slow?). All the code works for me but not hyperref. The links do not show up and moreover it somehow overrides the \tableofcontents command. There are no error messages so I am not sure what is going on. I am an advanced LaTeX user but still somewhat puzzled by this problem. I did solve the issue. As it turns out the amsart document class is not compatible with hyperref.

Congrats on an interesting and engaging presentation style. Can you do a video showing statistical formulas? The basic ones are sufficient; e.g., formulas for sample standard deviation, the calculating sample size would give me the start I need. Stay Safe. Kind Regards.

[@soswriting]

In LaTeX? Definitely! If you feel it would be helpful I'd be very glad to :) which formulae do you need exactly? Thanks for taking the time to comment, your kind words are very much appreciated!

@@soswriting One shows the calculation sample z-test (sigma known), t-test, sample standard deviation, sample variance, and calculating “r” from linear regression. I will take it from there. ☺️☺️☺️

[@soswriting]

@@robwin0072 Ah, you want me to explain the actual statistical formulas and how they work? I can do that :) I've got another LaTeX video in production at the moment, but I'm happy to make time to also cover other useful things. If you need it *very* quickly, one channel we always found helpful as undergrads is Khan Academy. They have a statistics playlist kzbin.info/www/bejne/q5nbpYiqlJJ6r68 but you might need to skip around the videos to find what you need. I'll add statistics to my to-do list in the meantime, since everyone hates it! I hope I can get it done in time to still be useful for you.

@@soswriting No, I am trying to find the LaTeX command that places the bar over x for means, in math format type, not text style.

[@soswriting]

@@robwin0072 Ah I see - that's quite straightforward, luckily! If you make sure you call the mathtools package in your preamble (and I think amsmath also contains this functionality), you can type \bar{x} inside your equation to get the bar over the top for the mean.
