Notes on the order of convergence, consistency and stability properties of newly derived schemes
In this paper, two numerical integration methods for solving Initial Value Problems (IVPs) in Ordinary Differential Equations (ODEs), namely “Third Order One Step Scheme (TOOSS) and Second Order One Step Scheme (SOOSS)” have been considered. The order of convergence, consistency and the stability properties of the schemes have been investigated. From the analyses, it is observed that SOOSS and TOOSS have...
Curriculum development and evaluation: New dimensions to enriching Mathematics Education in Nigeria
This paper makes a case for curriculum development and evaluation. It emphasized the new dimensions to enrich mathematics education in Nigeria. The paper therefore examined the meaning of curriculum. It highlighted issues involved in planning the mathematics education curriculum such as purpose of the curriculum, current knowledge level of students and materials. Also, it examined the practical aspect of developing the...
Degree of vertices and number of edges in a mixed graph
In the study of a graph theory, degrees of vertices and number of edges are among the important theoretical terms that are helpful in showing discrete structures and their properties. This study attempts to present the relationship between number of edges and degrees of vertices in a mixed graph. Key words: Graph, directed graphs, undirected graphs, mixed graph, degree of vertex, number of edges.
