Exponential Functions and the Number *e*

The purpose of this lab is to discover some properties of simple exponential
functions and to learn some ways of defining the number *e*
For the activities in this lab, you will be drawing graphs using our
"Graph Explorer" applet,

but it will also be useful for you to do at least some of the activities
"by hand" using a pencil and paper, so you might want to have some graph
paper available before you start.(You may also want to try doing the same
thing with your graphing calculator if you have one, or with any other
computer algebra system that you might have available on your computer.)

[Start
Lab Using Frames]
[Start
Lab Without Frames]

Either of the two buttons above can be used to start the
lab in a new browser window on top of this one. The button on the left
will run the lab in a framed window with the instructions in one frame
and the Graph Explorer in the other, and the one on the right will open
a window with just the instructions and a link to the Graph Explorer which
will open it in another window. If you want to be able to reposition the
text and graphs independently use the right button, but if you prefer to
have the two parts kept together without having to manage the two windows
yourself, then use the left button.
