The footnote at the end of section 4.4.6 on display-mode equations suggests using Insert/Math/Cases environment to enter the equation shown. However, doing so immediately results in errors in the default configuration, unless Layout/Document/Packages/Use AMS math is checked.
Thanks for the report, I'll fix this in the next version.
One or more of the following should happen: 1) AMS math should be on by default
Indeed.
2) The tutorial should indicate how to turn it on
Also indeed.
3) LyX itself should detect use of AMS math features and recommend turning it on, rather than giving cryptic messages about misplaced ampersands!
Yep. This feature will be in the upcoming LyX 1.4.0.
