Latex code for the "not equivalent" symbol

In summary, the Latex code for the "not equivalent" symbol is \neq or \not\equiv. To add this symbol to your Latex document, you can either use the code in your equation or use the command in your text. This symbol is different from the "not equal" symbol (\ne) and can be resized using the \scalebox command. Other similar symbols in Latex include \ncong and \not\sim, representing the concepts of not being congruent and not being similar, respectively.
