通过借助电脑工具探究自编自解题目“已知圆A:x2+y2=R2(R>0),定点B(a,0)(a>0),E是BC所在直线上的一点,且点E分CB的比为λ。(1)过点E作BC的垂线与AC所在的直线相交于点P,求点P的轨迹。(2)若AC交圆于另一点F,过E点作直线AC的平行线交BF于E蛐点,过点E与E蛐分别做直线BC与BF的垂线,求这两条垂线交点H的轨迹。”借助几何画板得出几个很重要的结论,并给出证明。 Through the use of computer tools to explore the self-solve problem "known circle A: x2 + y2 = R2 (R> 0), fixed point B (a, 0) , And the ratio of point E to CB is λ. (1) The point where the perpendicular between BC and E intersects the line where AC is at point P, and find the trajectory of point P. (2) If AC intersects at another point F, E point through the line for the AC parallel to the intersection of BF at E 蛐 point, over points E and E 蛐 respectively, the straight line BC and BF perpendicular to find the intersection of these two perpendicular H intersection trajectory. A few very important conclusions, and give proof.
