看着各种数字、字母以及图形堆砌在一起的数学,小脑袋是不是不自觉地开始迷迷糊糊了,而且就连梦里也净是(a+b)~2=a~2+b~2+2ab等各种杂乱的公式?忽然梦醒,以为会是山穷水复疑无路,柳暗花明又一村,但事实上却是离答案越来越远.那么,你会哇哇大哭扔掉书包,还是握笔凝思一切重来呢……初二的数学,初步进入数形结合的阶段.刚刚接触这个领域的学生很是迷惑,甚至情绪厌烦.这是正
Looking at the mathematics where various numbers, letters, and graphics are piled together, does the small head start unconsciously, and even the dream is net (a+b)~2=a~2+b~ 2+2ab and other kinds of messy formulas? Suddenly awake, thinking that it will be a mountain of water, no doubt, no doubt, but in fact it is farther and farther from the answer. Then you will wow and cry. After leaving schoolbags, I still have to hold a pen and meditation on everything. The second day of mathematics has initially entered the phase of combination of numbers and forms. Students who have just come into contact with this field are very confused and even emotionally bored. This is positive.
