I am wondering how to make a fraction in LaTeX small enough to fit on a line, or at least just a little larger. I could have sworn I had seen this before but I just cannot find it. In particular, I

\[ \frac{\fam0 a}{b} \] For my purposes, should such an issue arise, it is easily resolved by using \frac and so, while this example illustrates a shortcoming of \over and the need for something more robust, it …

It is nearly always best to use the slashed form for fractions in the text:

The command \over is a so-called "primitive" command that's available in Plain TeX and in LaTeX. \frac is a LaTeX-only command that builds on the \over macro to provide something that's much less likely …

Dec 8, 2016 · Often it looks better to use \tfrac if you are just wanting a numeric fraction as part of an expression, when the display fraction can look a bit spacey. Conversely if the fraction is already a …

With amsmath or mathtools you can write dfrac instead of frac, but since dfrac is used for inline fractions, it won't change anything for you in math environments. My workaround is using …

Jul 11, 2023 · How do you arrive at $1+\cos^2x = 2\cos^2\left (\frac {x} {2}\right)$ in your second line? That incorrect identity completely invalidates the rest of your work. You don't have to delete your …
