BibTeX entry

 @misc{ wiki:xxx,
   author = "Department of Mathematics at UTSA",
   title = "Double-angle formulas --- Department of Mathematics at UTSA{,} ",
   year = "2020",
   url = "https://mathresearch.utsa.edu/wiki/index.php?title=Double-angle_formulas&oldid=414",
   note = "[Online; accessed 6-February-2026]"

When using the LaTeX package url (\usepackage{url} somewhere in the preamble) which tends to give much more nicely formatted web addresses, the following may be preferred:

 @misc{ wiki:xxx,
   author = "Department of Mathematics at UTSA",
   title = "Double-angle formulas --- Department of Mathematics at UTSA{,} ",
   year = "2020",
   url = "\url{https://mathresearch.utsa.edu/wiki/index.php?title=Double-angle_formulas&oldid=414}",
   note = "[Online; accessed 6-February-2026]"
 }
