golub Posted February 9, 2020 Share Posted February 9, 2020 Hi, I can't do almost anything... Write a function that calculates the Euclidean distance for points: eucl(q1,z1,r2,z2). Calculate the distance of point pairs: (r1,z1), (r2,z2). Date: $r1=1; $z1=12; $r1=43; $z1=123; $r1=3; $z1=112; $r1=43; $z1=54; formula to the Euclidean distance: (r1,z1,r2,z2)=sqrt[(r1-z1)*(r1-z1) + (r2-z2)*(r2-z2)], where sqrt = square root. Can anyone help? Quote Link to comment https://forums.phpfreaks.com/topic/310000-euclidean-distance/ Share on other sites More sharing options...

ginerjm Posted February 9, 2020 Share Posted February 9, 2020 Are you trying to learn the calculation (this is not a Math forum) or how to code it using PHP (this is a PHP forum)?

golub Posted February 9, 2020 Author Share Posted February 9, 2020 Well, nothing... Php was such a faculty and were supposed to be simple tasks but this is some nightmare.

ginerjm Posted February 9, 2020 Share Posted February 9, 2020 PHP was such a faculty? What does that mean? Am I hearing that you don't know how to program this using php at all and you are in a class to learn such?
