20 1 1 year Zhejiang college entrance examination liberal arts mathematics solid geometric space rectangular coordinate system can give points?
Hello, I am a liberal arts student in Zhejiang College Entrance Examination on 20 10. Our teacher said at that time that rectangular coordinate system could be used, and the most complete pair must have been given. At that time, we specially added this chapter. Because as long as the system can be established, the vector must be much simpler than the ordinary geometric method. If you pass the calculation, I will give you a branch system and point coordinates, if you make a mistake. But as you know, the college entrance examination must be the pursuit of fairness. The construction of 20 10 liberal arts space geometry department is very difficult, and the construction calculation is fatal. So as a liberal arts student, I suggest that you must study the general geometric methods well.

The construction department is only a deputy, but it needs practice at ordinary times. In case it can be used in June this year, it still needs practice.
