2010 – Chain Rule AP CALCULUS
If you can’t do Algebra . . . . I guarantee you someone will do Algebra on you!
COMPOSITE FUNCTIONS Know: Need: Know: Need: REM: t(x)=1.0825(x) Order matters d(x)=.5(x) 10.83 10 Shirt for $20 10 20
f(x) COMPOSITE FUNCTIONS f(g(x)) g(x) - what is done first. g(x) x g(x) Let and y = outside u = inside function function
DECOMPOSE y = (outside) u = (inside). COMPOSITE FUNCTIONS
Derivative of __________________________________________________ a composite function 2 functions 2 parts Texas two step In Words: __________________________________________________________ d(outside)leave the inside alone*d(inside)
Chain Rule Leibniz Notation: In Words: __________________________________________________________ d(outside)leave the inside alone*d(inside)
Example 1: Example: Let y = u = _______
Example 2: Two steps:
Example 4: Example: Note:
Example 7: d(outside)*d(middle)*d(inside) Extended Chain: Ex: OR WORDS: Extended Chain:___________ Number of functions = number of parts
Derivative of the Absolute Value Function REM: Do not simplify. Use the Chain Rule.
General Rules: Working with number values Find the derivative. 1) f(x) + g(x) at x = 32) 2f(x) – 3g(x) at x =2 3) f(x)*g(x) at x = 24) f(x) / g(x) at x = 3 5) f(g(x)) at x = 26) (f(x))3 at x = 3 =
