Continuing the discussion from chatGPT creates Arduboy Game:
@bateske,
Any thoughts on adding this to the forum?

I actually never realized until now that ^2 is a square. I just use “square.”
In some programming languages ^ is the exponentiation operator rather than exclusive or. Most notably, most BASIC variants, Lua, and Haskell (though Haskell’s operators aren’t built in to the language)

?My thought is: why do we need this?
Because:
-
$x^2$is easier to type thanx<sup>2</sup>(x2). -
$\sum_{i=0}^n$is easier than trying to doΣ<sup>n</sup><sub>i=0</sub>(Σni=0). -
$\frac{1}{2}is easier than trying to represent1/2as a fraction without resorting to weird hacks like<sup>1</sup>⁄<sub>2</sub>(1⁄2). - Hunting for Unicode characters can be annoying.
-
$\Omega$is easier to write than to hunt down an Ω chracter (for those of you who like Ohms).
-
- Lots of other neat stuff.
Haha, on MacOS if you press Opt + Z you get the omega symbol.

On Windows there’s probably an Alt-code for it, but I keep losing my Alt-code ‘cheatsheet’
I only ever remember Alt+26 (→) because I use it more frequently than others.
I think you two will be the only people to use it but you are cool so good job. Math plugin enabled.

Not true. What prompted me to research and request the plugin be enabled was that the equations in a post by @dima-78 weren’t being properly displayed. With the plugin enabled, they now are:
We aren’t even talking about the arduboy really there and if it gets used primarily for non math purposes i’ll turn it off.
Yes,

Seriously though, it could be useful for writing some equations used for games such as for complex movement. Plus, there aren’t any downsides I can see to having it enabled. It doesn’t impact any other aspects of the forum.
No, but trigonometry does get used in games, so the subject being discussed is still relevant.
I expect it’ll find use when discussing the electrical side of things too. E.g. Now people can actually talk about 10 \Omega ($10 \Omega$) resistors witout having to deal with Unicode, or discuss things like V = IR with proper rendering.
In particular, I think it will be useful for helping people decipher mathematical explanations and understand their code equivalents.
E.g. for vectors:
-
\vec a \cdot \vec b →
dot(a, b) -
|\vec v| →
v.length()/length(v) -
\sqrt{v_x^2+v_y^2} →
sqrt(v.x * v.x, v.y * v.y)
Or for 3D/2D affine transformations and matrices:
\begin{bmatrix}
x \\
y
\end{bmatrix}
\begin{bmatrix}
cosine(angle) & sine(angle) & 0 \\
-sine(angle) & cosine(angle) & 0 \\
0 & 0 & 1 \\
\end{bmatrix}
x' = cosine(angle) * x - sine(angle) * y + 0
y' = sine(angle) * x + cosine(angle) * y + 0

You’re missing an e before the s 
(although I’m not sure if that was intentional)
Finally, you’re speaking my language!
Fixed it. I probably forgot it when I stopped to look up what the Greek equivalent of ‘k’ is called.
(My Greek is getting rusty through disuse.)
