What are the general skills for solving the penultimate problem of mathematics in college entrance examination?
In mathematics, analytic geometry has nothing special. The only thing is not to simplify all the numbers when calculating, not to take out the numbers in the root sign (except integers), and not to simplify the scores, so that the calculation will be simpler and more accurate. As long as the result is the simplest, it will be successful if the score is above 8!
