embed sage vars in html notebook cell
Again I feel like I'm missing something. I'm trying to add some mostly text content to a notebook cell, but I want to include an equation contained in a notebook variable. For example I have defined
var('u, v, w') x = u * v * w^2
And then I want to write a few paragraphs that includes the formula contained in x.
If I use the HTML editor and put something in dollar signs, it formats as math but doesn't eval the content, i.e. if I say $x$ then I just get a literal x in italics.
If I call the html() function, I can do something like
html('testing $'+latex(x)+'$') to manually substitute myself, but this gets formatted in fixed-width font for reasons I don't understand.
If I start a cell with
%html, then I can't figure out how to get the latex/html representation of the formula in x, but otherwise it formats it nicely. (I guess like an HTML editor cell)
Also, is there some documentation of how the different cell tags like %latex, %html, etc work?
