3.6 Calculating Higher-Order Derivatives
In short
You are expected to understand that taking higher-order derivatives mirrors familiar differentiation processes (i.e., 'function is to first derivative as first derivative is to second derivative'). You must be able to repeatedly apply differentiation rules, including the chain rule and implicit differentiation, to find second and subsequent derivatives.

What else do you need to know about Calculating Higher-Order Derivatives?
Conceptual understanding of what higher-order derivatives represent is emphasized over mere mechanical calculation.
Can you do these?
- I can find the second derivative by differentiating the first derivative, and repeat the process to find higher-order derivatives.
- I can recognize and use various notations for higher-order derivatives, such as f''(x), y'', d^2y/dx^2, and f^(n)(x).
How is Calculating Higher-Order Derivatives tested on the exam?
You must practice using correct mathematical notation for higher-order derivatives (e.g., d^2y/dx^2 vs. f''(x)) and apply procedures accurately. A common pitfall is poor notation or confusion when multiple differentiation rules (like the chain rule) apply sequentially. The AP Exam expects you to transition seamlessly between different notations and to justify the meaning of higher-order derivatives conceptually.
