[b]Math Modeling: [/b]The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences and engineering disciplines, as well as in non-physical systems such as the social sciences.[br][br][b]Step-1[br][/b]Use the Internet or other relevant sources to [b]collect the data[/b][br]Example: [br]Average Age Vs Average Heights of Male or Female[br][b]Step-2[/b][br]Enter your data like Points (x,y). x can be the first Variable. Two points are plotted for you ( You may edit them based on your data )[br]or you create lists [br][b]Type ----     [/b]listA= {x1, x2, x3,……  x10}    x1, x2 are all x-values[br]Type------   listB= {y1,y2,y3,y4,…….y10}    y1, y2, y3 are y-values[br]Type------  ( listA, listB)    to see all the points as coordinates

[b]Step-3[/b][br]Use [b]FitPoly( )[/b] command in GeoGebra to [b]get the Graph through the points.[br][br]Linear Curve: [/b]FitLine( list of pairs of Coordinates)[br][b]Polybomial: FitPoly({A,B,C,D,E},n)[br][/b]n : degree of polynomial[br]if you are not sure what n should be, then [br]type FitPoly({A,B,C,D,E})[br][br]Now onwards: You may Answer the following questions on a paper as well. ( Choice is yours)
