Maths and Postscript fonts

It's easy to use a postscript font (like helvetica) for the text of a L^ATEX document. What's harder is using the same font for maths. An easy, reasonable option is to use the mathptm package to put the maths into the postscript Times font and symbol font where possible.

Alternatively, use

• the mathpazo package (loads Palatino as the text font family and a mixture of the Pazo and CM fonts for math).
• the mathpple package (loads Palatino as the text font family and a mixture of artificially obliqued Euler fonts and CM fonts for math).

There are commercial alternatives, and free alternatives are under development.
