Sorry if a silly question, but is there a way to use variables in latex equations in pluto.jl markdown so that the equations change dynamically.  
Thanks,  
The new guy loving this language

I have not tried it for LaTeX, but in normal strings you can write a dollar-sign and then the variable ( as in ‘“My string has $var symbols”’, where the variable ‘var’ is defined elsewhere), to insert the value of the given variable in the string. I think that should work for LaTeX as well.

It’s a bit tricky because of the stupid stupid stupid TeX notation (`$$` instead of `\(\)`).

What you can do is use `Markdown.parse("String \$x = $x\$")` instead of `md"String $x = ???$"`, that way you _first_ build the string, and _then_ the markdown.

I have tried exactly that unsure if im missing something  
md"“”

```nohighlight
\lim_{h\to $(var)}

```

“”"  
Outputs the equation with $(var) in it

Oh also, iirc you can use double backtick for the math mode, instead of `\$`
