Many symbols used in mathematics, including calculus, take complex accessory symbols, which are placed above or below the main symbol in display text, but can be placed adjacent to the symbols in running text:

\[ \lim_{a \rightarrow \infty}f(x) = b \] |
\( \lim_{a \rightarrow \infty}f(x) = b \) |
\[ \int_0^1 f(x) dx = 3 \] |
\( \int_0^1 f(x) dx = 3 \) |
\[ \sum_{i=0}^n a_i = 1 \] |
\( \sum_{i=0}^n a_i = 1 \) |
In the symbols \(dx\), \(dy\) and so on that are common in calculus, the \(d\) is italicised as well as the variable.
