The definition of an Eulerian path is a path in a graph which visits each edge exactly once. Intuitively, think of tracing the path with a pencil without lifting the pencil's edge from the page.

One definition of an Eulerian graph is that every vertex has an even degree. You can check this by counting the degrees. Please see the related link for details.

What is the difference between an Euler circuit and an Euler path?

The difference between an Euler circuit and an Euler path is in the execution of the process. The Euler path will begin and end at varied vertices while the Euler circuit uses all the edges of the graph at once.


What did Euler do and please make it easy to understand?

Euler made important discoveries in fields as diverse as infinitesimal calculus and graph theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also renowned for his work in mechanics, fluid dynamics, optics, and astronomy. While I believe the preceding paragraph to be easy to understand, most of Euler's work is not.

Why is a legend important to understand a bar graph?

A legend is important because it tells about the scale of the bar graph and it also explains the colours in the graph. it becomes very easy to make or understand the bar graph


What is subgraph in given graph?

If all the vertices and edges of a graph A are in graph B then graph A is a sub graph of B.


Explain the difference between Euler and Rankine-Gordon formulas. Add also the graph.?

one fundamental difference: euler formula only considers failure due to buckling, while rankine-gordon also takes into effect the compressive stress.
