1.6 Exponential and Logarithm Functions
By the end of your studying, you should know:
On-screen applet instructions: There is a show-and-hide button for the natural log function. How are ex and ln(x) related?
ExamplesThe ground noise created by an airplane taking off at time t = 0 is measured in decibels, and is given by
where t is measured in seconds. How long will it be before the level of noise drops to 2 decibels?
