    A trivial problem . . . and solution


    Here's something that turned up from time to time.


    I type:

    . . \text{[m{a}th]}\theta\text{[/m{a}th]} is in a right triangle.

    . . And: \text{[m{a}th]}\backslash \text{tan} \backslash\text{theta} = \backslash \text{frac}\{\text{opp}\}\{\text{adj}\}\text{[/m{a}th]}


    And this is what is produced:

    . . \theta is in a right triangle.

    . . And: \tan\theta = \frac{opp}{adj}


    Note that the first \theta is smaller than the second one,  \theta.
    . . Yes, it's a trivial difference, I agree.


    Quite by accident, I found a correction for it.


    Precede the first \theta with a space.

    . . Type: . \text{[m{a}th]}\;\theta\text{[/m{a}th]} is in a right triangle.

    . . and we get: .  \theta is in a right triangle.



    Always glad to be of service . . .

    On my last few posts, I found that the "extra space" doesn't work.


    I type: .[math ]D[/tex] and [math ]D+E[/tex]

    . . and I get  D and D + E . . (The first D is smaller.)


    Then I type: .[math ] D[/tex] and [math ]D+E[/tex]
    . .
    (note the space before the D)

    . . and I still get  D and D+E


    The solution is one I've been trying to avoid: .\large{D}


    ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~


    I just completed some exhaustive experimenting
    . . and found some "rules".


    Upper-case letters

    The combination: A and A+x .has different-sized A's.

    The combination: L and L+x has same-sized L's.

    The sizes are the same for: . L,\:M,\:O,\:U,\:W,\:Z
    All the other upper-case letters appear in two sizes.

    These can be corrected by the "extra space" trick
    . . except for A,\,B,\,D.


    Lower-case letters

    The combination: a and a+x has different-sized a's.

    The combination: e and e+x has same-sized e's.

    The sizes are the same for e and o only.
    All the other lower-case letters appear in two sizes.

    These can be corrected by the "extra space" trick
    . . except for k\text{ and }m.


    Why these exceptions? . . . I have no idea!


    ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~


    It finally occured to me . . .

    I just spent an inordinate amount of time on a most trivial matter:
    . . a barely discernible difference in the size of fonts.

    I must get a life . . .

    I think it's discernible enough. Do you know about the \displaystyle command? I assumed you were adding a space because it's a lot faster than typing \displaystyle, as a shortcut basically. Before the forum upgrade, \displaystyle was selected by default, now it's not.

    Actually I think we might use \, (or \: or \; or "\ " without quotes) as a shortcut.

    Test without anything D versus D+E.

    Test using space  D versus D+E.

    Test using "\ " without quotes \ D versus D+E.

    Test using \; \;D versus D+E.

    Test using \: " alt="\" /> versus D+E.

    Test using \, \,D versus D+E.

    Test using \displaystyle \displaystyle D versus D+E.

    It keeps fractions the smaller size

    Test using \, \,\frac{A}{B} versus \frac{A}{B}

    Test using \displaystyle \displaystyle\frac{A}{B} versus \frac{A}{B}

    Hello, undefined!


    Those are great tips . . . Thank you!

    I didn't think of adding a space with \; etc . . . *blush*



    If I want to enlarge a single fraction, I use \dfrac{2}{3}

    . . So we have \dfrac{2}{3} instead of \frac{2}{3}



    When I use \boxed{ } around a fraction,
    . . it automatically gives me the larger version.

    . . . . . \frac{2}{3}. . . . . . . \frac{2}{3}

    . . \boxed{\frac{2}{3}} . . \boxed{\frac{2}{3}}


    If I prefer the smaller font, I reduce the size with \tfrac{2}{3}

    . . \boxed{\tfrac{2}{3}}. . . \boxed{\tfrac{2}{3}}
