I'm good at the traditional method of solving three-dimensional geometry, but I can't solve it. I'm not good at the vector method, so what should I do?

Vector method is better, because you can avoid the trouble of finding the angle, in the examination of three-dimensional geometry will not be too difficult, easy to find the coordinates, coordinates of the most basic things you know how to find it, if not, you go to the teacher to ask, and you take a few questions with the vector to answer the question to see, to study their **** the same ... ... to find the angle of the ha, the distance of the ha, there are formulas ... ... pay attention to a little bit, then ... ... actually nothing difficult! ...pay attention to a little on it...actually nothing difficult...
