20 0 4年高考 (浙江卷 )理科第 15题 :设坐标平面内有一个质点从原点出发 ,沿x轴跳动 ,每次向正方向或负方向跳 1个单位 ,经过 5次跳动质点落在( 3 ,0 ) (允许重复过此点 )处 ,则质点不同的运动方法共有种 .如果我们将问题作如下推广 :1 一维中整点问题设坐标平面内有一个质点
2004 College Entrance Examination (Zhejiang Volume) Science Question 15: Let there be a particle in the coordinate plane starting from the origin and jumping along the x-axis, jumping 1 unit each time in the positive or negative direction. After 5 beats the particle falls on (3,0) (Allow to repeat this point), there are altogether different kinds of methods for the movement of particles. If we expand the question as follows: 1 There is a particle in the coordinate plane for the whole point problem in one dimension.
