How does one insert a backslash or a tilde into LaTeX?

I have tried using \text{\~{}} to draw a tilde in math mode. However, this only produces a superscript tilde.

I have looked around at many pages such as this one: http://www.artofproblemsolving.com/Wiki/index.php/LaTeX:Symbols

and surprisingly, I can't find where to draw a tilde in math mode (not under or above a character - just a single tilde character). If I just use ~, then nothing appears.

    What does "sim" stands for? This is a short for what? – rph Nov 14 '18 at 13:25

    I believe "sim" is short for similar. This symbol is often used to relate similar things, such as in linear algebra where ~ means two matrices are row-equivalent (which is a similarity between those matrices). – define cindy const Mar 27 at 4:19

Is \sim an option for you? It looks like a tilde.
