When itcomes to a meaningful life, we might think of love, happiness and health. Alife filled with meaning is what most of us want for ourselves. Then, whatmakes a meaningful life?Manyresearchers agree that a meaningful life comes down to three factors (因素): havinglong-term goals, believing that one’s life matters, and feeling that one’s lifefits together and “makes sense”.But we believe there is more to consider. Sometimeslife enables us to experience small moments of beauty. When people are open toappreciating (欣赏) suchexperiences, these moments may improve how they see their own life. We callthis experiential appreciation (EA).
北师大初中九年级数学下册二次函数与一元二次方程2教案
教学目标：1.知道二次函数与一元二次方程的联系，提高综合解决问题的能力．2.会求抛物线与坐标轴交点坐标，会结合函数图象求方程的根.教学重点：二次函数与一元二次方程的联系．预设难点：用二次函数与一元二次方程的关系综合解题．☆ 预习导航 ☆一、链接：1.画一次函数y=2x-3的图象并回答下列问题(1)求直线y=2x-3与x轴的交点坐标； (2)解方程2x-3=0(3)说出直线y=2x-3与x轴交点的横坐标和方程根的关系2.不解方程3x2-2x+4=0，此方程有 个根。二、导读画二次函数y= x2-5x+4的图象1．观察图象，抛物线与x轴的交点坐标是什么？2.求一元二次方程x2-5x+4=0的解。3.抛物线与x轴交点的横坐标与一元二次方程x2-5x+4=0的解有什么关系？（3）一元二次方程ax2＋bx＋c=0是二次函数y＝ax2＋bx＋c当函数值y=0时的特殊情况.二次函数y＝ax2＋bx＋c的图象与x轴交点的横坐标与一元二次方程ax2＋bx＋c=0的根有什么关系？
北师大初中七年级数学下册多项式与多项式相乘教案
解：(ax2＋bx＋1)(3x－2)＝3ax3－2ax2＋3bx2－2bx＋3x－2.∵积不含x2项，也不含x项，∴－2a＋3b＝0，－2b＋3＝0，解得b＝32，a＝94，∴系数a、b的值分别是94，32.方法总结：解决此类问题首先要利用多项式乘法法则计算出展开式，合并同类项后，再根据不含某一项，可得这一项系数等于零，再列出方程解答．三、板书设计1．多项式与多项式的乘法法则：多项式和多项式相乘，先用一个多项式的每一项与另一个多项式的每一项相乘，再把所得的积相加．2．多项式与多项式乘法的应用本节知识的综合性较强，要求学生熟练掌握前面所学的单项式与单项式相乘及单项式与多项式相乘的知识，同时为了让学生理解并掌握多项式与多项式相乘的法则，教学中一定要精讲精练，让学生从练习中再次体会法则的内容，为以后的学习奠定基础
北师大初中七年级数学下册单项式除以单项式教案
光的速度约为3×108米/秒，一颗人造地球卫星的速度是8×103米/秒，则光的速度是这颗人造地球卫星速度的多少倍？解析：要求光速是人造地球卫星的速度的倍数，用光速除以人造地球卫星的速度，可转化为单项式相除问题．解：(3×108)÷(8×103)＝(3÷8)·(108÷103)＝3.75×104.答：光速是这颗人造地球卫星速度的3.75×104倍．方法总结：解整式除法的实际应用题时，应分清何为除式，何为被除式，然后应当单项式除以单项式法则计算．三、板书设计1．单项式除以单项式的运算法则：单项式相除，把系数、同底数幂分别相除，作为商的因式；对于只在被除式里含有的字母，则连同它的指数作为商的一个因式．2．单项式除以单项式的应用在教学过程中，通过生活中的情景导入，引导学生根据单项式乘以单项式的乘法运算推导出其逆运算的规律，在探究的过程中经历数学概念的生成过程，从而加深印象
