So I have a PIAF.
Desmos graphs are I guess okay better than nothing, but I thought why not try out TactileView to produce graph.
I tried two random equations by selecting latex as math input.
y=4x^3-5x^2+3x-3
and
\lim_{x\to 4} \frac{3x^2+3x+2}{x^2+2x+1}
I just wanted to get a non boring graph.
But somehow each time tactileview tells me that there is a syntax error in my math input. It hinted me to write 3*x instead of 3x for example, which I did but same result. I don't want to install mathtype cause latex is the only thing I know anyway.
Is this tactileview that parses it so badly? Not good given it costs roughly like cad$800 with tax.
Any help or resource to get help would be appreciated.

Re: TactileView and LATEX
Sadly TactileView does not actually support latex input. It only supports showing the latex output in print of what is brailled. The manual is an absolute mess for how it is written.
It only accepts mathType or mathMML pasted in or linear math typed in.
Are you kidding me
Humanware! Can't you even write a manual correctly? Not to mention that the tactileview website is like 2000s and there are childish errors in the french translation that an elementary school kid would not do.
And they expect us to pay $800+ for this trash? No thank you!
Thanks so much @Ryan Hunsaker. It's really really appreciated.
GnuPlot
I would recommend trying out GnuPlot. It has its own syntax for equations not LaTeX, but its free and extremely powerful and you don't have to buy MathType or type MathML by hand which is very verbose. It is extremely customizable so you can make the graph better for tactile reading, although I have never tried to use it to make graphs for a machine like that; I've just made visual graphs to turn in for assignments. Otherwise if you still want to use TactileView, you can convert LaTeX to MathML with Pandoc (type your equations surrounded by dollar signs, then convert from Markdown to HTML5 with MathML like this: pandoc equations.md -o equations.html -t htmp5 --mathml). But I think GnuPlot is way better than DesMos.

Ooh that is interesting I never heard of it, thanks! I am curious how it is better than desmos :) I'll keep you all posted!
