[Solved] Formatting when aligning equations at the =

Post by 22878 »

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?

Image

Code: Select all

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

alignr nospace{int f(x)dx} # {}={} # alignl nospace{ 2 x^2 + 3 x - 1 } over {alignc {x^{1/3}}}dx ##

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.

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.

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.
