Lin Chaoning, who has just passed the heavy pressure of the college entrance examination and entered college life with great expectations, is the successor of socialism in the new era with moral, intellectual, physical, artistic, labor and mathematics headaches. When Lin Chaoning sat in the advanced mathematics class, looking at the increasingly difficult to understand function derivatives, listening to the teacher's passionate teachings and writing on the blackboard that were even worse than those in high school, Lin Chaoning remained silent and said that I didn't understand but was greatly shocked. Thank you, God, for taking me to a place where there is no mathematics! Along with the profound mathematical terminology, Lin Chaoning's eyelids connected. My family really can't stand it anymore. Let me get rid of it! Lin Chaoning's consciousness returned to him and his whole body ached with pain. After listening to the conversations of people in his ears for several days, Lin Chaoning realized that I couldn't be... I had traveled through time! It was also worn on a sick man.
Purpose: The author's best wish in advanced mathematics classes is to study mathematics well.
