[Solved] Formatting when aligning equations at the =

Postby 22878 » Thu Jul 16, 2020 11:43 pm

As you can see from the attached image, the numerator and denominator are shifted to the left of the fraction bars. Is there any way to fix this?

Code: Select all   Expand viewCollapse view
size 28 nospace { matrix{
alignr nospace{int f(x)dx} # {}={} # alignl nospace{ 2 x^2 + 3 x - 1 } over {x^{1/3}}dx ##
alignr {} # {}={} # alignl int left({ nospace{2 x^2} over {x^{1/3}} } + { nospace{3 x} over {x^{1/3}} } - { {1} over {x^{1/3}} }right)dx ##
alignr {} # {}={} # alignl int (nospace{2 x^{5/3} + 3 x^{2/3} - x^{1/3}})dx ##
alignr {} # {}={} # alignl 2 cdot { {3} over {8} } x^{8/3} + 3 cdot { {3} over {5} } x^{5/3} - 3 cdot { {3} over {2} } x^{2/3} + C ##
alignr {} # {}={} # alignl { {3} over {4} } x^{8/3} + { {9} over {5} } x^{5/3} - { {3} over {2} } x^{2/3} + C} }

Your formula code applied in my LibreOffice 6.2.8:

Do you see how the numerators and denominators in the fractions are shifted to the left side of the fraction bar instead of being centered? That's what I'm trying to fix.

Ahhh... I meant the integral signs in your image above.

The modified first line seems to work as you expected (I put an "alignc" command into the denominator):

Code: Select all   Expand viewCollapse view
alignr nospace{int f(x)dx} # {}={} # alignl nospace{ 2 x^2 + 3 x - 1 } over {alignc {x^{1/3}}}dx ##

As formatted with OpenOffice 4.1.7 on Mac OS 10.14.6
Use Format → Alignment → Centered then
size 28 {
int f(x)dx
stack { ~=~ int {
{2 x^2 + 3 x - 1} over {x^{1/3}}
} dx ~~~~~~~~~~~
# ~=~ int { left (
{ {2 x^2} over {x^{1/3}} } +
{ {3 x} over {x^{1/3}} } -
{ 1 over {x^{1/3}} }
right ) } dx ~~~~~~
# ~=~ int {
{2 x^{5/3} + 3 x^{2/3} - x^-{1/3}}
} dx ~~~~~
# ~=~ 2 cdot { 3 over 8 } x^{8/3} +
3 cdot { 3 over 5 } x^{5/3} -
{ 3 over 2 } x^{2/3} + C
# ~=~ { 3 over 4 } x^{8/3} +
{ 9 over 5 } x^{5/3} -
{ 3 over 2 } x^{2/3} + C ~~~~
}
}
It's more important to get the math right than spend hours fussing over tiny formatting details.

I am using format > alignment > centered, and your code doesn't line everything up, but it does make it so the numerators and denominators aren't shifted to the left. What are these ~? It seems you are just adding spaces to line things up? Also, I know there were mistakes in my first post, I fixed them in my image before you responded.

Note: I used the formatting recommended here: https://wiki.openoffice.org/w/images/3/ ... ide3.3.pdf to align the equations at the equals sign.

Does anyone have a solution? I used the method recommended in the Math guide. I cannot understand why everything is shifted to the left.

I cannot understand why everything is shifted to the left.

Because you have used the alignl (= align left) command inside the formula. Use the alignc (= align ceter) command for the relevant parts of the formula, as I pointed it above. Use the braces for the parts of the formla what you want to align center.

You requested left alignment for your fraction with:
alignl nospace{ 2 x^2 + 3 x - 1 } over {x^{1/3}}dx

I gave you a solution and included a picture of the formatted equation on my system. You seemed to be dissatisfied with the result on your system, but did not give any precise indication of why. "Your code doesn't line everything up" is too vague. To receive any further assistance from me, you must provide more information. It will be helpful if you attach a screen image (as a picture), the exact Math syntax you used (as text and not a picture), and what adjustment you want to make.

There are known, and solved, Math font formatting problems on awful Windows so perhaps you have a problem at the operating system level. Have you fixed the problem from that link? I, thankfully, run MacOS instead of odious Windows, so if your code formats correctly on my system, I may not be of much help to you.

I will probably decline to help with adjusting tiny formatting details which would be a waste of my freely-offered time. However, If you choose to focus on that, go right ahead, and perhaps others will have suggestions for you.

This topic has concerned centering in formulas. You asked about a new subject, vertical alignment, so a new topic was created for you: Match vertical alignment in multi-line formula.

We prefer to keep to one subject per topic. Subjects are not considered related simply because they are from the same person. You'll find replies to the new subject there. View your posts is a simple way to find your posts, even if they have been split to a new topic. Most recent posts will be at the top.

Your original formula works for me, when I modified it by the usage the "alignc" command in proper bracing.


This is amazing. This is the correct solution to my problem, because it uses the method recommended to line up equations at the equals sign, so you don't have to use the space hacks, which don't completely line up the equals signs, like this does, plus you need another stack or something to get the left half of the equation at the top with the other method. Bravo, Tibor.
