General ⇒ Line breaking inside array

[twoflower]

Hello, could you please tell me how to force latex break the lines nicely even inside the array environment? When I have a long line there, it just flows over the right edge of the page. I can manually add the line breaks using \\, but it is far from the desired result.

Thank you very much.
