I'm writing a math paper using TexShop that is almost entirely original but I got help with a trig proof; I found a formula in a book that I improved upon, and then got help finding a number series that completed my improvement. I would like to cite the help I got and at least one book but I don't know the proper place to put citations, inline or at the end of the paper. Do I do

I found a formula in a book that I improved upon

When you introduce the formula, cite the book, e.g., the following formula is proposed by Author X [1]:

and then got help finding a number series

Presumably you got help from someone. You can acknowledge that help at the end of your main body in an acknowledgements section. (Use \section*{Acknowledgements}.)


While the details are dependent on the venue where you are publishing, most mathematical papers will put the full citations at the end but reference them in the midst of the text (e.g., via a citation number).

You can format these automatically if you use LaTeX, and the AMS provides widely used packages for formatting.


Consult the style guide of the journal in question.

Different style guides have different requirements on how different types of citations are to be performed. Harvard is different to IEEE which is in turn different to APA.
