AP 预备微积分 – 9.5 换底公式

大家好，本期视频给大家带来的是AP 数学 -分章讲解 9.5 换底公式。余下的章节火热更新中，敬请期待！ Hello everyone! In this video, we will look at AP Pre-Calculus - 9.5 Changing Base Formula. The rest of the chapters are coming soon, so stay tuned! 章节9.4 首先复习了对数函数的幂法则，之后我们使用了幂法则来证明了换底公式，换底公式可以转换任何对数为自然对数的竖直增长 In Section 9.4, we first review the power laws of logarithmic functions. Then prove the change-of-base formula. This formula allows us to rewrite any logarithm using natural logarithms and helps us understand their vertical growth. 对AP数学感兴趣的同学们可以先浏览视频，希望喜欢的同学们可以点赞，加关注，有问题请私 Students who are interested in AP Pre-Calculus can first watch the video.
