## Union and Big Union Symbol in LaTeX

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.

## 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!
