In mathematics, the union symbol is used to represent the union of two sets. The big union symbol is used to represent the union of several sets. In LaTeX, these symbols can be represented using the `\cup`

and `\bigcup`

commands.

In mathematics, the union symbol is used to represent the union of two sets. The big union symbol is used to represent the union of several sets. In LaTeX, these symbols can be represented using the `\cup`

and `\bigcup`

commands.

To write the union symbol in LaTeX, use the `\cup`

command. For example:

```
$$
A \cup B
$$
```

$$ A \cup B $$

This represents the union of sets $A$ and $B$.

To write the big union symbol in LaTeX, use the `\bigcup`

command. For example:

```
$$
\bigcup_{i=1}^n A_i
$$
```

$$ \bigcup_{i=1}^n A_i $$

This represents the union of sets $A_1, A_2, \dots, A_n$.

It’s as simple as that!
