2010年上海高考数学理科试题较往年平稳很多,大部分都是比较常规的问题,但平凡中蕴含着不平凡,比如理科第23题:已知椭圆Γ的方程为x~2/a~2+y~2/b~2=1(a>b>0),点P的坐标为(-a,b).(1)若直角坐标平面上的点M、A(0,-b)、B(a,0)满足(?)=1/2((?)+(?)),求点M的坐标; 2010 Shanghai college entrance examination mathematics science subjects a lot more stable than in previous years, most of them are more conventional problems, but ordinary contains an extraordinary, such as science 23 questions: known ellipse Γ equation is x ~ 2 / a ~ 2 + the coordinate of point P is (-a, b). (1) If point M, A (0, -b), B (a, 0) satisfy (?) = 1/2 ((?) + (?)), find the coordinates of point M;
