我们都是高一年级的学生,在学校领导和我们数学老师的支持、鼓励下办起了“数学课外活动小组”。当我们学习对数换底公式时,除了认真学习教材,完成了课内、课外作业,还利用下午的课外时间和星期天,阅读了一些数学资料,选作了一部份(包括编写了一部份)对数知识方面的习题。在这个过程中我们发现。一,关于求对数的值,证明对数等式,解对数方程中的很多例题、习题,对数换底公式起了决定性的作用。二,过去的一些高考数学题,竞赛试
We are all students in the first year of senior high school. Under the support and encouragement of school leaders and our mathematics teachers, we have set up a “Mathematics Extracurricular Activity Group.” When we learned the formula of the formula, we did not only carefully study the teaching materials, completed the in-class and extra-curricular activities, but also used the extracurricular time and Sunday afternoon to read a number of mathematical data and selected one part (including the preparation of one part). ) Logarithmic knowledge exercises. In the process we discovered. First, on the value of the logarithm, to prove the logarithm equation, to solve many of the examples in the logarithmic equations, exercises, and logarithmic exchange formula play a decisive role. Second, some of the past college math problems, race test
