Solution of the SIR Mathematical Model for the Spread of Covid-19 Using GeoGebra

Abstract

This study aims to find solution of the SIR modelling for the spread of Covid-19 in populations of an area for normal, new normal and lockdown conditions using GeoGebra. This research consists of two stages of numerical assessment of mathematical model completion using GeoGebra spreadsheets and building GeoGebra Applets for system simulations. The results show that the SIR model for the spread of Covid-19 can be solved numerically by using GeoGebra spreadsheets, by first changing the system of differential equations into systems of difference equations. Furthermore, by using existing facilities in GeoGebra, GeoGebra Applets can be arranged to simulate system dynamics for normal, new normal and lockdown conditions.
