I would like to solve a problem but I am not able to do it. Precisely I am creating figures and I should insert mathematical formulas. The first thing I do is to create a
.tex source and then edit it in Adobe Illustrator. I can change the symbols, but, for example, the square root is not perfectly viewable and in its place I see a rectangle with a cross. There is some strategy to solve this problem?
I have attached the related images created first with the LaTeX, and then edited with Adobe Illustrator.
