## Closed Captioned Video: Algebra Applications: Exponential Functions, Segment 4: How Is Earthquake Magnitude Measured? # Description

An earthquake is an example of a seismic wave. A wave can be modeled with a trigonometric function. Using the TI-Nspire, students link the amplitude to an exponential function to analyze the dramatic increase in intensity resulting from minor changes to magnitude.
A Video Transcript is available for this tutorial.

## Closed Captioned Video: Algebra Applications: Logarithmic Functions # Description

In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of logarithmic functions. Such disparate phenomena as hearing loss and tsunamis can be explained through logarithmic models.

## Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 1: What Are Logarithms? # Description

The mathematical definition of a logarithm is the inverse of an exponential function, but why do we need to use logarithms? This segment explains the nature of some data sets, where incremental changes in the domain result in explosive changes in the range.

## Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 2: Hearing Loss # Description

We live in a noisy world. In fact, prolonged exposure to noise can cause hearing loss. Students analyze the noise level at a rock concert and determine the ideal distance where the noise level is out of the harmful range.

## Closed Captioned Video: Algebra Applications: Logarithmic Functions, Segment 3: Tsunamis # Description

In 1998 a devastating tsunami was triggered by a 7.0 magnitude earthquake off the coast of New Guinea. The amount of energy from this earthquake was equivalent to a thermonuclear explosion. Students analyze the energy outputs for different magnitude earthquakes.
