Graphing a circle can seem like a daunting task, but with the right approach, it’s actually quite straightforward. This article will walk you through 9 simple steps to help you graph a circle with ...

ABSTRACT: The vertex connectivity k(G) of a graph G is the minimum number of nodes whose deletion disconnects it. Graph connectivity is one of the most fundamental problems in graph theory. In this ...

Abstract: A vertex set D ⊆ V is considered a dominating set of G if every vertex in V − D is adjacent to at least one vertex in D. We called a dominating set D as a paired-dominating set if the ...

Any point P with coordinates (\(x,~y\)) on the circumference of a circle can be joined to the centre (0, 0) by a straight line that forms the hypotenuse of a right angle triangle with sides of length ...

Find the equation of a circle with radius 3 units and centre (0, 0). The radius, \(r = 3\) and \(r^2 = 9\), so the equation of the circle is \(x^2 + y^2 = 9\). What is the radius of the circle given ...
