20 1 1 Is it difficult for Anhui college entrance examination in mathematics and science?
Personally, I think this year's test paper is about students' pure skills, 16, basic skills, required points, 17. If you don't say anything, directly establish the rectangular coordinate system, 18, which is a problem of starting to distance yourself. Depending on your usual practice level, 19 has two more problems to prove, although the second problem can definitely be proved by using the nature of logarithm. Finally, it can be changed into, the right side is equal to 0, (specifically, self-study), 20 questions, the first question and the second question. Should it be okay? 2 1 The problem is not an ellipse or a straight line, but a parabola. Needless to say, you can compare my statement and review the exercises. Dude, this year's topic, for some people, is simply to let them go to college! ! I wish you do well in the exam this year. This year's question is based on the foundation, not the difficulty. Good question!
