The Chain Rule

  • Think of the function you are trying to differentiate as a function composition.
  • You can informally think of this as involving an “outer function” and an “inner function.”
  • Some problems involve a composition of three or more functions!
  • You will be using the Chain Rule throughout the rest of calculus, so it is important to learn it really well!
