Hello,
This is my first time writing to the group.
I recently used, and convinced my Calculus group, to use OO Math in
order to input a Calculus II project for a presentation. We ran into a
problem when we could not find a symbol for “Evaluated from a to b”,
such as the small attached image (I hope that is allowed), or something
similar to this:
|b
f(x)|
|a
We ended up just creating it in a graphics program and creating jpgs
from the OO Math file, which does not seem like the correct way to do
this at all.
Hi Michael
The best I've come up with is:
f(x) size*1.7 "|"_a^b
which doesn't look too bad though you might prefer the vertical line to
be longer. (The factor of 1.7 is to compensate for the standard
subscript and superscript size being 60% of full size - thus the a and b
are 102% of full size, and the vertical line is 170% of full size.)
I also tried along the lines of:
f(x) left lline stack{b # "" # a} right rline
(You can omit the words "left" and "right" if you have the "scale all
brackets" option turned on by default, as I do.) But this has the
unwanted right-hand line, and I can't work out a way to omit it since
Math expects brackets to be in pairs. Someone may come up with a way
round that.
Hope that is some help?
Andy
