Question
latex - sum in Lyx
Hello,
I'm trying to write a sum (with indexes) in Lyx.
Normally I would write the command \sum_{i=1}^{n} but this doesn't work in Lyx,
the part "i=1" isn't underneath the sum symbol and when I write "^" it jumps into the uperscript of "i=1"
thanks

It seems you must use the GUI nithis case, "raw" LaTeX subscripts/superscripts don't work.
See http://heather.cs.ucdavis.
Greek letters, summation and integral signs, and so on, are available via Math->Math Panel. Each square within that panel displays a few summary symbols; click on it to see the entire choice of symbols.
To put limits on a summation or integral sign, use Index and Exponent as for subscripts and superscripts above. (Use the arrow keys to make sure the cursor is next to the summation or integral sign first.) If you wish the limits to go "north" and "south" of the integral sign instead of "northeast" and "southeast," use the int, sum, min, max, etc. items in the Functions window within the Math Panel.
