Posted: Thu Mar 18, 2004 4:45 pm Post subject: Equation editor integration limits 


am I being an idiot?? How do I specifiy the limits for integration within the equation editor? I looked in the helpfile and found the bit about from and to, but that seems to just endup printing what I type in and an upside down questionmark, which I assume means a parse error or some sort? Can someone paste a simple example of how to use it here please? Basicaly I want to say integrate f(x) between a and b.
Thanks,
Alan

I don't have it handy, and simply don't use that math editor at all, but ...
A question mark often indicates a spot to put things you want into an autogenerated formula. Try putting upper and lower bounds where there are quesiton marks to see what you get.
If doing math, there are many more powerful programs out there. If dead serious, I'd look into Mackichan software, or even the math editor in WordPerfect 8 (now much better in later versions of that and Word.) It's all MUCH easier ith clickandpaste than typing pseudonames. Corel (Wordperfect) still has academic versions that make the purchase within reason.

Try
Code:  int from a to b f(x) dx 
or
Code:  int from {x=0} to {x = infinity}{1 over {1+x^2}} "d"x 
I wouldn't agree with David about pointandclick vs. pseudocode  if you've ever used latex you should find OOo's code familiar. For text + some equations OOo is fine.

thanks for the help, I was just being an idiot. From the help documentation I had concluded that writing
from a to b int f(x) dx was how it was done

Ok, now i've run into another slighty problem.... basicaly I'm trying to show integration in my doucment, and now I want to show that I have yet to apply the limits using square brackets. is:
stack {b # a}[x over 2]
the way to do this or is there something else i'm missing about from and to?
Thanks,
Alan

Try this:
Code:  left[ a over b right]_a ^b 
PD: For this kind of questions, the Math forum is best
