    Abstract: Nigeria, a developing nation is experiencing the overwhelming effects of her exponentially ever-increasing population. This paper is aimed at projecting the future population of Nigeria using the exponential and geometric growth models from 1991 and 2006 population censuses of Nigeria. The resultant effects are clearly evident for all stakeholders ... Show More

    Abstract: The essence of this paper is to analyze the stability and implementation of a newly derived explicit fourth-stage fourth-order Runge-Kutta method. Efforts will be made to carry out a comparative analysis with an existing classical fourth stage fourth order explicit Runge Kutta method. The implementation on initial-value problems revealed that the m... Show More

    Abstract: This paper introduces Euler’s explicit method for solving the numerical solution of the population growth model, logistic growth model. The Euler method is a first-order method, which means that the local error (error per step) is proportional to the square of the step size, and the global error (error at a given time) is proportional to the step s...
