Lesson

If time is a problem, you may opt to do only one of the case studies. However, they are all excellent review material for the unit.

Case Study 1- Notes

For part (a), multiply through by the common denominator and rearrange the equation in general form.

For part (g) use the internet and do a search on the "golden section" or the "golden ratio". You might also find some information by doing a search on "Fibonacci sequences".

Case Study 2

The key to setting up the equation is to sketch a graph of the data. This is shown below for the information in part (a) (i).

You thus have three points on the parabola so you should be able to find its defining function using the techniques learned in the unit.

Case Study 3

This is a straight forward application similar to several other problems in the text.

Activity

Depending on the time you have, complete at least one of the Case Studies on pages 61 & 62 in your text. If you have the time and interest complete two or all three of them.

Test Yourself

There are no test items for the Case Studies.
