MAT 1221Survey of Calculus Section 2.5 The Chain Rule http://myhome.spu.edu/lauw
Expectations • Use equals signs • Pay attention to units • Problem 2: Formally answer the question
Reminder • Exam 1, next Thursday • Look at the comments from the grader • Look at the solutions online • Make improvements
Preview • We know how to find derivatives of Power functions, polynomials, products, quotients. • Section 2.5: Composite functions • We will look at the chain rule. • Focus on the special case : Extended Power Rule
Recall (Composite Functions) • Suppose
Recall (Composite Functions) • Suppose • Then,
Classwork 1 • Practice compositing functions • We are going to check the answers together in 1.5 min.
The Chain Rule: Part I If f and g are both differentiable, then is also differentiable
The Chain Rule: Part II Version 1 Meaning • Find and then substitute • Multiply by
Expectations • Must show the “formula” step when using the Chain Rule/ Extended Power Rule
