Wikipedia:Vertex-transitive graph#0 | In the mathematical field of graph theory, an automorphism is a permutation of the vertices such that edges are mapped to edges and non-edges are mapped to non-edges. A graph is a vertex-transitive graph if, given any two vertices v1 and v2 of G, there is an automorphism f such that f ( v 1 ) = v 2 . {\displaystyle f(v... |
Wikipedia:Vertical line test#0 | In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. If a vertical line intersects a curve on an xy-plane more than once then for one value of x the curve has more than one value of y, and so, th... |
Wikipedia:Vertical tangent#0 | In mathematics, particularly calculus, a vertical tangent is a tangent line that is vertical. Because a vertical line has infinite slope, a function whose graph has a vertical tangent is not differentiable at the point of tangency. == Limit definition == A function ƒ has a vertical tangent at x = a if the difference qu... |
