About Derivatives
Derivatives measure instantaneous rates of change and slopes of tangent lines. Students learn derivative rules and apply derivatives to analyze function behavior and solve optimization problems.
Derivatives are fundamental to calculus and essential for physics (velocity, acceleration), optimization problems, curve sketching, and understanding how quantities change.
Calculus: Derivatives
Define derivative as rate of change; compute basic derivatives; apply to motion, optimization, and graph behavior.
This medium level worksheet:
Apply product/quotient/chain rules; analyze increasing/decreasing and extrema.
Key Concepts
- Derivative as instantaneous rate
- Differentiation rules
- Critical points, slope, concavity
Prerequisite skills
Limits/continuity basics; algebraic manipulation; function transformations.
Teaching Strategies
Link average to instantaneous rate; build from power rule; use derivative tests on graphs; integrate real applications.
Assessment ideas
Test derivative calculation using various rules. Include application problems (related rates, optimization). Ask students to analyze functions using first and second derivatives. Use real contexts (motion, economics).
Common Challenges
Sign mistakes in rules; confusing slope vs. concavity; unit interpretation in rates.
Real-World Applications
Velocity/acceleration, marginal cost/revenue, growth/decay rates.
Extension Activities
Sketch f, f', f'' relationships; solve a simple optimization and verify with derivative tests; check derivatives with tech.
Parent Tips
Have them explain what the derivative represents in a context before calculating.
