2.9 Derivative of lnx
This is the ninth lesson in the Derivatives Unit. The lesson contains Guided Notes, homework, SmartBoard lesson, and all solutions. Don’t forget the added bonus of a math joke embedded into the Smartboard lesson ☺! You may have also opted to purchase the video lesson to the notes.
In this lesson, students will learn how to differentiate lnx. Prior to this lesson, students should be aware of log properties. If they are unfamiliar with the properties of logs, it is a good idea to review them. By the end of the lesson, students will be able to differentiate lnx with the Product, Quotient, and Chain Rules. They will also understand how to take the derivative of lnx involving trig functions, implicit differentiation, and finding tangent lines. Finally, students will see how knowing log properties can help them with more difficult derivatives. They must understand that they can only apply log properties when taking a derivative of a log function.
I hope you find the notes easy to follow. Please feel free to offer any suggestions on how to make them better as well! Through a community of collaboration, we can better challenge and support our students and their learning process.
All the best,
