数Ⅲ微分計算#14/26【三角関数の微分(計算編)】公式適用のための見方から｜演習必須！

Differentiation of trigonometric functions becomes complex when it intertwines with differentiation of product, quotient, and composite functions. Practice repeatedly using problem sets! ▼This is a video lesson channel where a current math teacher (from a combined junior and senior high school) carefully explains all topics in high school mathematics, following the textbook. The lessons are primarily blackboard-based, with each video lasting approximately 10 minutes, allowing you to thoroughly learn about two pages of the textbook. Ideal for home study, preparation and review, and flipped classrooms. ▼ High School Math Playlist [   • 数学Ⅲ　微分計算  ] [   • 数学Ⅲ 微分の応用  ] [   • 数学Ⅲ 積分計算  ] For other topics, please watch them in order from the [Playlist] tab on the channel. ▼【Recommended for those who:】 ・Want to learn high school mathematics systematically ・Want to efficiently prepare for and review lessons ・Want to pinpoint and strengthen weak areas for entrance exam preparation ▼【Examples of use】 ・Pre-lesson learning (compatible with flipped classrooms) ・Preparation for regular tests ・Building a strong foundation for university entrance exams ▼【About the creator】 Mathematics teacher at a combined junior and senior high school / Graduate of the Department of Mathematics, Faculty of Science, Kyoto University / Produces high school level lesson videos We strive to create lessons that emphasize "why we solve it that way?" rather than "how to solve it?" This channel is created as a stock-type learning material that can be reviewed repeatedly over the long term.
