TeXShop or LaTeXiT are two applications that can be used to produce mathematical text for labeling figures.

Gary Gray from the Penn State University has provided a nice collection of PDF processing applications to properly crop text that has been typsest with TeXShop and using the text as outlines to label figures in Adobe Illustrator.

As I posted earlier, I have a simple little ''AppleScript app that will properly crop the PDF by dragging and dropping the file on the app''. Here is the procedure we use to label figures---it includes the cropping aspect.
The general idea is that you can create the labels in a .tex file, convert the fonts in the resulting .pdf file to Postscript outlines, open that .ps file in AI, and then copy and post those outlines in the AI figure file. The steps are as follows:
http://www.esm.psu.edu/mac-tex/PDF-Processing-Apps.zip
assume it is called "test.pdf".
it is called "labels.tex".
resulting labels.pdf file on "TeX Font Outliner.app"
resulting .ps file will automatically open in AI. Copy the labels from the .ps file and place the labels in the figure you saved in part (1), i.e., in test.pdf
to test-AI.pdf (so that you will have your original file for later editing) and then it will crop that file by removing all white space and it will name the cropped file test.pdf.
That's all there is to it. I have only tested this with AI CS2 and CS3, though it should work with earlier versions with a slight modification of the AppleScript. Both apps are universal binary.
We have labeled hundreds of figures this way over the past couple of years and it really works exceedingly well.
