一个学期的复习,数学长进了多少?能独立而快速地解答一些容量较大的综合题了吗?下面为你提供的这些题不是新题,而是百做不厌的经典题,做好、记住这些题,肯定对你是极有帮助的.题一已知过原点O的一条直线与函数y=log_8x的图象交于A、B两点,分别过点A、B作y轴的平行线与函数y=log_2x的图象交于C、D两点,(1)证明C、D与原点。共线;(2)当BC平行于x轴时,求点A的坐标.
A semester review, mathematics grow into how much? Can independently and quickly answer some of the larger comprehensive questions? The following questions for you is not a new title, but do not tire of the classical questions, do a good job, remember Live these questions, it is certainly very helpful to you. Problem I Known point O of a straight line and the function y = log_8x the image of the intersection of A, B two points, respectively, over point A, B for the y-axis parallel Line and the function y = log_2x the image at C, D two points, (1) to prove C, D and origin. Collinear; (2) when BC parallel to the x-axis, find the coordinates of point A.
