Tasostasouliss Posted December 18, 2018 Report Share Posted December 18, 2018 Hey! So I have this issue about my HL Math IA references. I basically had to find a proof for the catenary shape, and I consulted this site over here: https://proofwiki.org/wiki/Equation_of_Catenary/Formulation_1/Proof It is proofwiki. But I know that generally wikipedia is not considered reliable. But in this case it is Mathematics, and it shows a proof which I went over a trillion times- and it is a correct, valid, reliable proof. A proof which I used. And I cannot find the same proof anywhere else. Should I cite this site? Will I lose points for it being from proofwiki? Or will noone care? Edit: Is this site even a part of wikipedia? How could I cite this in APA? Any help appreciated! Thanks! Reply Link to post Share on other sites More sharing options...
kw0573 Posted December 18, 2018 Report Share Posted December 18, 2018 There will not be penalties for using such a site in the IA. You should be able to find the latest APA format for a website somewhere online. 1 Reply Link to post Share on other sites More sharing options...
