I teach mathematics, chemistry and physics to high school students at an online school in Australia. This channel is where I post the tutorial videos I record for my students and others. My LaTeX files can be downloaded from my GitHub page.
Hi! Thank you for this very helpful video! I'm wondering if we are able to make changes to the axis arrow? The default one looks like a stealth tip, are we able to change it to a latex tip somehow?
One would write "axis line style=-latex" in the axis environment options. For example, \begin{axis}[axis line style=-latex] ... \end{axis} will achieve this.
I'm enjoying your material (informative, concise & relevant), but would you consider using a larger character size in the code window and zooming in on the PDF to improve visability a little. Unfortunately I do not possess a 76 inch screen.
Hello good day. So, I deduced a very simple formula for tracing 3D figures in the LaTeX graphic environment, if anyone is interested I can send it by email..

One tip: you can do a lot of the same stuff with way less complexity in Matlab, Mathematica, Maple, and even Excel (or Google Sheets), Geogebra, and export the output as a .pdf and then include it into your latex project.
It would be nice to see a video dedicated to asymptotes and how to deal with rational functions. I found a LaTeX package called asymptote but it is rather terse and the documentation is not very useful. It is not clear if the package works with tikz/pgf either. I do realize that we will still have to find the asymptotes using regular algebra techniques before we can include them in our plots.
I have a few problems with indentation say like : (i) P(E) = P(F) --> this mean.................................. that the............. ////// My problem is wanting my line to start in this case from 'this mean' and not go all the way left. haha, I hope I am making sense. please make a tutorial on that.
I wonder if an align environment is the answer? Remember that one must always use an odd number of ampersands to make everything line up properly. In your case, you would have an ampersand directly before the "this".
Learning LaTeX and it's associated "add-ons" is a truly humiliating experience. Every time I think I have learnt something well and my chest is starting to puff up along comes another package like tikz/pgf with its massive manual I am feel as if I am back to square one! Is anyone actually a complete LaTeX expert?
There are few videos that deal with asymptotes so this is nice to see. Plotting rational functions is pretty much impossible without knowing how to deal with the asymptotes. Thanks!
Great video. I would like to see more of these but separated into multiple files rather than one master document. I find hard to keep track of things with multiple lines of code being either activated or hidden. Simple might be: Here is how we do plot A, plot B, plot C etc. Thanks Peter!
Midway through the video these questions arose in my mind. 1) There is another command \bar{} that produces overstrike. It is a bit shorter 'strike' than \overline{} uses. Does it matter which one is used? 2) In the preamble I put mathmode inside the macros definition. For example: ewcommand{\mean}[1]{$ \overline{#1}$}. Then I just call the macro with \mean{} rather than $\mean{x}$. You seem to prefer the latter. Why? Thanks.
(1) I think \bar vs \overline is a matter of taste more than anything. See: tex.stackexchange.com/questions/22100/the-bar-and-overline-commands. (2) I prefer my way because maths will generally surround my macro, e.g. $x + \mean{x} = y$.
In regards to the figure options [htbp] my understanding is the is order that LaTeX will decide to put the 'floats'. Here-top-bottom-page and if we only give it a single option e.g. [h] then it will put it there. I found that LaTeX is pretty smart about where the floats should go and have typically not messed with until perhaps the very end the document is in its final stages. Thanks for sharing a nice video. There are not enough LaTeX demos out there.
I agree that LaTeX normally gets the placement right. Having said that, when students come to LaTeX fresh from Word, they often crave a lot of control over placement as they think LaTeX is getting it "wrong".
I agree with the equation numbering. I don't think I have ever come across a published paper with equation numbers on the left. They are typically on the right side. Also it could lead to some confusion when you have numbered lists (enumerate) in LaTeX. Another weird "quirk" of LaTeX is to label tables on the bottom rather than on top.
Hi Amanda, the text editor I'm using here is called Texmaker and my LaTeX distribution is MacTeX. Having said that, I'd recommend using the online system called Overleaf. I find it to be a better fit for my needs than Texmaker and MacTeX.
@@wduandy It can be heavy reading at times but the pgfplots package manual can be found at ctan.org/pkg/pgfplots?lang=en. Page 35 would be a good place to start.
Thank you so much for this wonderful video. What GUI are you using for latex workflows? I only work on overleaf, because long back i found keeping track of packages was crazy
Hi Abdullah, no worries. These days I actually prefer to work in Overleaf myself. In the past, though, I used to work more in Texmaker. Overleaf is so good though, isn't it?
Glad it was useful. We change this in the addplot options. Instead of writing \addplot[<->] we can write \addplot[->] or \addplot[-] depending on whether we just want an arrowhead on the right end or on neither end of the graph.
Hi, glad you found it useful! Suppose you wanted your horizontal axis to be labelled X and your vertical axis to be labelled Y, then in the axis options make sure you include the code: xlabel=$X$, ylabel=$Y$,
