Bitopological Approximation Space with Application to Data Reduction in Multivalued Information Systems

Abstract: In this work we generalize Pawlak approximation space to bitopological approximation space. One binary relation can define two subbases of two topological spaces. Membership, equillity and inclusion relations using rough approximations are defined and studied in bitopological aapproximation space. Some new measures that measure the accuracy and the quality of approximations are defined and … Read more

Statistics overview

Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real life studies. Statistical analysis involves the process of gathering and evaluating data and then summarizing the data into a mathematical form. Statistics is a term used to summarize a process that a … Read more

Numerical Weather Prediction

You turn on the television, and often the first channel that pops up is the weather. It’s going 24/7 with predictions that go from weekly all the way down to hourly, with conditions that go from humidity to temperature. But what goes on behind the scenes is heavily entrenched in mathematics– meteorology’s backbone is a … Read more

The Mathematics of Our Universe

Abstract In this report, we start by defining key aspects of classical Lagrangian mechanics including the principle of least action and how one can use this to derive the Euler-Lagrange equations. Momentum and Conservation laws shall also be introduced, deriving relations between position, momenta and the Lagrangian of a given system. Following this, we develop … Read more

Teaching of mathematics

INTRODUCTION As mathematics is a compulsory subject upto the secondary level, access to quality mathematics education is the right of every child. Developing children’s abilities for mathematisation is the main goal of mathematics education. In the words of David Wheeler, it is “more useful to know how to mathematise than to know a lot of … Read more

History of mathematics

INTRODUCTION After the early mathematicians from Egypt, Babylon, and Greece, mathematics still continued to pave its way toward so many ideas and discoveries. The successors of the Greeks in the history of mathematics were the Hindus of India. The Hindu civilization’s record in mathematics dates from about 800 B.C., but became significant only after influenced … Read more

Mayan Mathematics, Calendar, Astronomy and Maya Today

The mathematical system of the Mayan Civilization was considered the most sophisticated system in the continent of America. The most noteworthy discovery of the Mayans is their understanding of the concept of zero. The Mayans used three simple symbols representing different values in Mathematics to help the uneducated easily understand numbers and other concepts of … Read more

Importance of Technology in Mathematics education

LITERATURE REVIEW Introduction Introduction of technology has a very large impact on the educational environments, and has made many changes in the way students learn and the way they are being taught by their teachers. This has finally caused the teachers’ roles to slightly change. Students are responsible for learning by being active in increasing … Read more
