[Mathematical experiment of the track problem]

After establishing and solving the mathematical model of the track problem, a mathematical experiment on the problem is designed in this paper. Mathematical modelling is established and the solution is obtained. It has been proved that the three factors, namely the curve of the child, the length and the angle of the stick, influence the track of the toy considerably. Using the MATLAB software, the effect of each factor is modelled clearly. Furthermore, several meaningful findings are obtained by detecting the track of the toy.
