The best fitted curve of wau bulan / Nur Atiyah Husna Suhaimi, Nurul Akmal Hanisah Besar and Nurrul Ain Nazieha Abdullah

Wau Bulan is one of the foremost well-known sorts of kites in Malaysia. Its name is from the crescent moon-like shape of its lower section. Wau Bulan is relates to the mathematical concept of equations such as geometry, equation of a curve, angle, and so on. From previous studies, the authors have sought the equations of curves for Wau Bulan. However, the equations resulting from two different equations namely Bezier equation and Hermite equation produce different images. Therefore, further studies need to done to determine the best equation for the Wau Bulan. The purpose of this study is to find the best-fitted curves for Wau Bulan by comparing the error between models of Wau Bulan. Both equations are convert to get new coordinates of the y-axis by using solve plot and by converting the parametric equation to a non-parametric equation. To analyse the error, a model of actual Wau Bulan is uses to compare the error between the actual with Quadratic Bezier curves and the error between the actual with Cubic Hermite curves. The coordinate of the x-axis and y-axis of the actual model is identified using GetData software. The relative error is applied to recognize the least error of the curves in order to find the best-fitted curve. The final result of the least square error shows that the Bezier equations have the smallest error and it is conclude that the Bezier equation model is the best fitted model of Wau Bulan.
