Can you use vector method for solid geometry in college entrance examination?

It's entirely possible. The year before last, I did a lot of simulation questions and real questions, basically all of which can use vector method. Half of solid geometry has two sets of answers, namely common law and vector method, and there are a few questions that can't establish coordinate system, but there are almost no real questions in the college entrance examination. It's just that the vector method is sometimes not the simplest, and sometimes it's difficult to find a suitable origin and see the coordinate system through the vector method. For example, in 2009, the college entrance examination in Jiangxi was still very sad. So it's best to do both methods and not be afraid of anything.
