[Solved] Upper & lower limits after closing square bracket

Postby ooswinton » Sat Jan 20, 2018 12:00 pm

I have attached the procedure I used to assign upper and lower limits to the closing square bracket (following the evaluation of an integral). The limits are inserted by adding ^4 and _1 to the formula.

ORIGINAL POST
I have no problem entering upper and lower limits to the integral (int) symbol.
However, after evaluating the integral, the expression should be in square brackets with the upper and lower limits after the closing bracket.
How do I use maths to enter these limits (from <>to <> does not work).

On the Libre office forum, I have seen the suggestion to use Isub and Isup but I cannot get this to work either.

Just a tip/guessing:

use an empty parameter for the lsub/lsup

You are right. The "from {} to {}" construct does only accept very few preceding elements (left opening of the construct).

I don't know if everywhere, but in some regions (among them Germany) at least, the standard notation for the evaluation of a definite integral based on an integrating function would require a more general use of "from {} to {}". It is not supported.

A workaround I used once in a while when I was not yet retired, was (given by a simple example here):
Code: Select all   Expand viewCollapse view
int from{-%pi over 4} to{%pi} sin( x) dx= left[{-cos(x)}right] matrix{""sup {%pi} ## " " ##"" sub {-%pi over 4}}
There may be complications in less simple (scaling) cases.

(Appendix:)
You may ask Giordon Stark how he did it here: https://www.quora.com/What-do-the-squar ... an?share=1.
Would you mind to link in your question or finding in the ask.libreoffice site here? Did Regina answer there?
Or was it the late (Sigh!!) libreofficeforum.org (much better than the askbot thing)?

I presonally would use a vertical line instead of square brackets, which have other meanings.
int from{-%pi/4} to{%pi/4} cos(x) dx = left none sin(x) right rline rsup {+%pi/4} rsub {-%pi/4}
