I am using Macbook Air, OS X 10.9.2. I want to create vector illustration of mathematical and organic formulas, so I can use those vector illustrations for T-shirts.

Examples:

How can I do that on Macbook Air? I am now studying Lynda.com-Illustrator CS6 One-on-One Fundamentals, but that does not help so much.

For the mathematical formulas, I would definitely use LaTeX, since it gives you high quality typesetting for math stuff. You don’t have to install LaTeX yourself if you don’t want to, because there are online LaTeX renderers which let you export the result to e.g. pdf.

Therefore, if you go to this site and enter the correct code for your formula

```
$$\lim_{n\to\infty}\int_0^1\int_0^1\dots\int_0^1\
cos^2\left(\frac{\pi}{2n}(x_1+x_2+\ldots x_n)\right) dx_1 dx_2\ldots dx_n$$
```

you can download it as pdf which can be directly used in Illustrator.

The chemical formulas are a bit harder, because I haven’t found any online editors which give you vector graphics, but I’m sure that there are free programs you can install which do that. Before you go this way, you should carefully check whether the structural formula you want isn’t something which can be found in Wikipedia or in another database. There, you might find a svn/eps/pdf file of the structure.
