  1. Warm-Up: February 12, 2013 • Solve for x. Give both an exact solution and a decimal approximation (3 decimal places).

  2. Homework Questions?

  3. The Natural Base, e Section 6.6

  4. Essential Questions • What are e and ln? • How can we use e and ln to solve equations?

  5. The Natural Base • Remember π? • π is always 3.14… • e is an irrational number, just like π • e is always 2.718… • e is called the natural base

  6. Natural Logarithms • A natural logarithm is a logarithm with base e • Notation: ln x = logex

  7. TI-83 • [LN] button is below [LOG] button • [2nd] [LN] for e^(

  8. You-Try #1 • Use your calculator to evaluate the following:

  9. Log Properties with ln • All properties of logarithms still apply to natural logarithms, including:

  10. Example 2 • Solve for x. Give both an exact solution and a decimal approximation (three decimal places).

  11. You-Try #2 • Solve for x. Give both an exact solution and a decimal approximation (three decimal places).
