随着新课程改革的推进,研究性探索题进入了中考题,成了探索题中的一个新亮点,现举例说明.例1(上海2004年)数学课上,老师出示图和下面框中条件:如图1,在直角坐标平面内,O为坐标原点,A点坐标为(1,0),点B在x轴上且在点A的右侧,AB=OA,过点A和B作x轴上的垂线,分别交二次函y=x2的图象 With the advancement of the new curriculum reform, research exploration questions have entered the examination questions and become a new bright spot in the exploration questions. Now for example. Example 1 (Shanghai 2004) in mathematics class, the teacher shows the diagram and the conditions in the box below : As shown in Figure 1, in the Cartesian coordinate plane, O is the origin of coordinates, point A is (1,0), point B is on the x-axis and on the right side of point A, AB=OA, over points A and B Vertical lines on the x-axis, intersecting the image of the second-order y=x2
