Math Problem Statement
Solution
The image contains some useful rules about derivatives, particularly focusing on linearity and the product rule. Let me summarize the content for you:
Linearity of Derivatives:
-
Sum Rule: If and are differentiable at the point , then:
-
Scalar Multiplication Rule: If is differentiable at the point and , then:
-
Difference Rule: If and are differentiable at the point , then:
The Product Rule:
If and are differentiable at , then: The proof is outlined using the definition of a derivative, starting with:
Would you like further explanations or a worked example of one of these rules? Here are some follow-up questions:
- What is the practical application of the product rule in solving calculus problems?
- How can the sum or difference rules simplify differentiating polynomial functions?
- Can you explain how these rules extend to higher derivatives (e.g., second derivatives)?
- Could you show an example where both the product and sum rules are used together?
- How does the proof of the product rule reinforce the importance of the limit definition of a derivative?
Tip: Mastering the product rule is essential for understanding more complex rules, such as the chain rule and quotient rule!
