Overview
This resource extends students’ understanding of differentiation to include trigonometric, logarithmic, and exponential functions, as well as composite, product, and quotient functions.
Students will explore and apply the chain rule, product rule, and quotient rule to a variety of problems, including those involving related rates of change.
The lesson provides clear proofs, intuitive explanations, and worked examples designed to reinforce conceptual understanding while building procedural fluency.
Learning Objectives
By the end of this lesson, students will be able to:
- Differentiate standard functions including ( \sin x ), ( \cos x ), ( \tan x ), ( \ln x ), and ( e^x ).
- Apply the chain rule to differentiate composite functions.
- Use the product rule to differentiate products of two or more functions.
- Use the quotient rule to differentiate ratios of functions.
- Solve related rates problems involving differentiation with respect to time.
- Interpret derivatives in applied contexts such as growth, motion, and geometry.
