轴对称在社会生活、生产中应用十分广泛,有关它的试题新颖、灵活,备爱备受中考命题者青睐,现举两例以飨读者.一、利用轴对称确定一次函数关系式例1我们设想用电脑模拟台球游戏,为简单起见,约定:①每个球袋视为一个点,如果不遇到障碍,各球均沿直线前进;②A球击B球,意味着B球在A球前进的路线上,且B球被撞击后沿A球原来的方向前进;③球撞击桌边
Axicon symmetry is widely used in social life and production. The questions related to it are novel and flexible, and preparation for love is highly favored by the proposition examiners. Now two examples are given to readers. First, use axisymmetric to determine a functional relationship. Example 1 Imagine using a computer to simulate a game of billiards. For the sake of simplicity, it is agreed that: 1 Each bag is regarded as a point. If no obstacles are encountered, each ball follows a straight line; a 2A ball hits B ball, which means that B ball moves forward in A ball. On the course, and after B ball is hit, it goes in the original direction of A ball; 3 balls hit the table
