This calculator finds x and y intercepts, vertex, focus and plots the quadratic function. The calculator will generate a detailed explanation for each of these computations.Every graph has certain properties that can be used to describe it. An important property of graphs that is used frequently in graph theory is the degree of each vertex. The degree of a vertex in G is the number of vertices adjacent to it, or, equivalently, the number of edges incident on it. We represent the degree of a vertex by deg(v) = Net>Partition>Degree>Input ! to view, select File>Partition>Edit ! if you need to reverse the direction of each tie first (e.g. lends money to -> borrows from): Net>Transform>Transpose ! Influence range (a.k.a. input domain) ! Net>k-Neighbours>Input ! enter the number of the vertex, and 0 to consider all vertices that

Since the Eulerian tour uses each edge exactly once, every vertex has even degree. Also, the ﬁrst vertex v has even degree because the walk leaves it in the beginning but returns to v at the end. Proof (⇐=): Our strategy is to construct an Eulerian tour knowing that we have a connected graph G(V,E) with each vertex having an even degree.

An example might be the word-search graph from CS223/2005/Assignments/HW10, which consists of all words in a dictionary with an edge between any two words that differ only by one letter.A planar graph is a graph on a plane where no two edges are crossing each other. The set of regions of a map can be represented more abstractly as an undirected graph that has a vertex for each region and an edge for every pair of regions that share a boundary segment. Hence the four color theorem is applied here. Finding the Axis of Symmetry and Vertex of a Parabola. Look again at the figure below. Do you see that we could fold each parabola in half and that one side would lie on top of the other? The ‘fold line’ is a line of symmetry. We call it the axis of symmetry of the parabola. We show the same two graphs again with the axis of symmetry in red.

I need to prove that two graphs (say, H and G) which are isomorphic and their vertices have the same degree. So far, I have the summation of the degrees across all vertives is 2|E| and since if two graphs are isomorphic, then they must have the same number of edges. Therefore, each corresponding vertex in H and G must have the same degree. I need to prove that two graphs (say, H and G) which are isomorphic and their vertices have the same degree. So far, I have the summation of the degrees across all vertives is 2|E| and since if two graphs are isomorphic, then they must have the same number of edges. Therefore, each corresponding vertex in H and G must have the same degree. To analize a graph it is important to look at the degree of a vertex. One way to find the degree is to count the number of edges which has that vertx as an endpoint. An easy way to do this is to draw a circle around the vertex and count the number of edges that cross the circle. To find the degree of a graph, figure out all of the vertex degrees.

A graph has a total degree. The total degree of a graph is deﬁned by If G is any graph, then the sum of the degrees of all the vertices of G equals twice the number of edges of G. If G is a graph with m edges and vertices {v 1,v 2,...,v n}, then XN i=1 d(v i) = 2m By this we also know The total degree of a graph is even. We also know In any graph, there are an even number of vertices of odd degree. If G is regular of degree k, then every vertex is incident to k edges. Every edge is incident to 2 vertices and at one vertex the edge will be adjacent to k −1 other edges and at the other vertex the edge will be adjacent to k − 1 other vertices. Therefore L(G) will have each vertex adjacent to 2k − 2 other vertices and hence is regular of Denote the degree of vertex i by &(i) and let D(G) = diag (&(l),&(2), . . . , c&(n)) be the diagonal matrix of vertex degrees.

In directed graph to count the degree of a vertex (any edges connected with it) I was just counting -1 and +1 in every row. That worked. The problem is - the degree is multiplied by 2 everywhere in the undirected graph, because the matrix is naturally "converting" line edges into two arrow edges, like on the picture. This is a maximum point, it's a maximum point for this parabola. And now I want to find two more points so that I can really determine the parabola. Three points completely determine a parabola. So that's 1, the vertex, that's interesting. Now, what I'd like to do is just get two points that are equidistant from the vertex.
