For any circle π is the number 3.14 in the equation: circumference = 2π x radius or π x diameter. So π is circumference diameter. Starting from that (as a definition of π) we can show that the area of a circle is πR 2.

WebA line graph L(G) (also called an adjoint, conjugate, covering, derivative, derived, edge, edge-to-vertex dual, interchange, representative, or theta-obrazom graph) of a simple graph G is obtained by associating a vertex with each edge of the graph and connecting two vertices with an edge iff the corresponding edges of G have a vertex in common … WebA polar equation describes a curve on the polar grid. The graph of a polar equation can be evaluated for three types of symmetry, as shown in Figure 6.2.2. Figure 6.2.2: (a) A graph is symmetric with respect to the line θ = π 2 (y-axis) if replacing (r, θ) with ( − r, − θ) yields an equivalent equation. Webexistence of a Moore graph with (n;d;D) = (3250;57;2) is a challenging open problem in graph theory. If D 3, Moore graphs exist only for (n;d) = (2D +1;2), which are cycles of odd length.
