Understand what a doubling time or half life means and how to use it compute a growth rate or vice versa.
  • What is doubling time and how do you find it?
  • What is half-life and how do you find it?
  • If you want your investment to double in value every three years, at what rate of interest would you need to invest it assuming it is compounded continuously?
  • If your investment on stocks is losing half its value every two years, how can you find and interpret the associated decay rate?
  • How do you use the Equation Solver on a TI Graphing Calculator to solve a doubling time or half-life problem?
  • How do you solve the exponential equation 2 = 1e^(3k)?
This lesson does a great job of explaining doubling time and half-life and showing how to find / use these values in real-world situations. The topics are explained very well, and all steps involved in solving the 2 problems presented using a TI graphing calculator are very clear. Solving by hand using paper is also shown in this lesson.
