How to use curly brackets in latex?

Question

I need to write curly brackets (braces) "{}" in the overleaf latex document. How can I write it?

Answer 1

You need to use the backslash (\) with { and } to write curly brackets in the latex document. Without a backslash, it will not show braces.

Here is an example.

\{($x_1$, $y_1$), ($x_2$, $y_2$)\}

The above syntax will display the following: 

 {(x₁, y₁), (x₂, y₂)}
