  • What is the difference between \dfrac and \frac? - TeX
    with \frac: the actual context implies the decision above For example, if you have a complicated mathematical expression in the middle of some array environment (which, by default, employs text-style math), you can use \dfrac to force the use of displaystyle math mode for the fraction \dfrac and \tfrac are from the amsmath package
  • How to get a little frac - TeX - LaTeX Stack Exchange

  • What is the meaning behind the common fraction notation $\\frac{a}{b}$?
    Then what does $\frac{3}{4}$ of the cake mean? Or is it just a shorthand way of writing (where the denominator is the number of equal parts into which something is divided and the numerator is the number of taken parts), for example, “two thirds of a rope” is $\frac{2}{3}$? Can someone explain the meaning behind this notation with examples?
  • What is the difference between \over and \frac? - TeX
    \frac is a LaTeX-only command that builds on the \over macro to provide something that's much less likely to throw unexpected errors if the user doesn't handle the syntax of the \over command just right Assuming you have the amsmath package loaded, the \frac command is defined as follows:
  • Practical consequences of using \over vs. \frac? - TeX
    \[ \frac{\fam0 a}{b} \] 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 does not illustrate to me any reason to eschew \over when it does yield the desired output
  • Proof of $\\frac{d}{dx}e^x = e^x$ - Mathematics Stack Exchange
    I'm working through the proof of $\\frac{d}{dx}e^x = e^x$, and trying to understand it, but my mind has gotten stuck at the last step Starting with the definition of a derivative, we can formulate
  • Numbers are very small in numerator and denominator using \frac
    Also, the reason why it is called dfrac is because it is a \frac that is in display mode, which in general makes things larger \documentclass{article} \usepackage{amsmath} \begin{document} Large Fraction: $\dfrac{1}{2}$ Small Fraction: $\frac{1}{2}$ \end{document} BTW, if you want to do a fraction like "1 2" (with the slash) use \sfrac
  • math mode - How to do fractions - TeX - LaTeX Stack Exchange
    Your question is basically about mathjax usage in websites (such as Math SE), but fortunately, \frac or \dfrac command (for 'better' fractions) work with mathjax – user31729 Commented Dec 3, 2014 at 15:40
