- Section 7.2 homework problems are due today.
- Your assignment for section 7.3 is to be completed on-line: please do that before next Tuesday.
- Logs are, by definition, the inverses of the exponential functions:
- The laws of logarithms are reflections of the properties of
exponentials:
- The derivation of the derivative of the natural log function is
easy, given our work on inverses:
- Another way to define the log function is as an anti-derivative
of the "weird power" x-1:
Symmetry help us to understand the absolute value in this result: an antiderivative of the odd function 1/x is an even function ln(|x|).
