Ocean observations. amoeba sisters video recap nature of science answers Jul 20, 2017 · 1. @DeanP a cycle is just a special type of trail. A graph with a Euler cycle necessarily also has a Euler trail, the cycle being that trail. A graph is able to have a trail while not having a cycle. For trivial example, a path graph. A graph is able to have neither, for trivial example a disjoint union of cycles. – JMoravitz. 1)Finite connected graph (with vertices of even degree except 2 or 0 with the odd degree) will have a Euler path. 2)But Euler path can also be present in the disconnected graph as shown in the following picture. 3) Doubt does following graph have Euler path, My answer ,No as all vertices are not in same connected component.
