Do dogs know the bifurcation locus - Li Zhou A dog runs at speed r and swims at speed s, with r > s. For a fixed point A in a lake with a straight shoreline, where are all the points B in the lake such that the direct swimming path from A to B takes the dog the same time as the fastest indirect swimming- running-swimming path? We give a simple geometric solution to this bifurcation-locus problem. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
