I am writing a thesis. While writing chapter 3, I need to refer an equation from chapter 2. How could I do this? I do not want to repeat the same equation in every chapter. Kindly help. Thanks a lot for the help.
There are several packages that would do the job. I would recommend to use the
hyperref package in combination with the
hyperref should be loaded last and
cleveref afterwards. The former one enables the base functionality for hyperlinks and the latter one extends it (it automatically determines the type of the referenced object and will precede the number accordingly with equation, table, figure). Then assuming you labeled your equation you can simply reference it with
eq: is not mandatory but it helps in keeping the overview.
