1. The problem statement, all variables and given/known data What is the difference between a cycle & a circuit? (Definition not reqd, guidance reqd with the figure attached) 2. Relevant equations No 3. The attempt at a solution See the attached figure. According to this figure the walk AB, BC, CE, EF, FD, DA represents a cycle or not because we have a repeated vertex B?? (in my view its not a cycle because we have a repeated vertex in the middle).However it represents a circuit because there is no repeated edge. Some body please guide me whether i am correct or not & give an example of cycle from the figure. Sorry for the picture not fitting with size. I have created it on paint & then saved it but i dont know how to get rid of extra white space. Zulfi.
