Exponents on Video!

Class time seems to just fly by! Sometimes we get hung up on a difficult problem and time seems to  d r a g  and sometimes we cover so much material in such a short time that it just seems to fly by.

I know some of us are still struggling with exponential functions. Well, help is here. I've got some brief video taped lectures you can watch to help you with this material over the weekend if you need it. The movies are of an instructor from the University of Idaho.

In order to watch the video you need to download the free realaudio player from here. (It's a little more than 11 Mb so if you have a slow internet connection this isn't a very good option for you.) After that, just click on the link below for help with the topic of your choice!

• A Review of the Laws of Exponents
  (4 min. 6 sec.)


• The Definition of an Exponential Function
  (7 min. 37 sec.)


• Sketching the Graphs of Exponential Functions
  (8 min. 34 sec.)


• The Definition of the Function e^x
  (5 min. 39 sec.)

Let me know what you thought of the video in the comments to this post. Did it help you learn? Is it clear and easy to follow? Should I post more of these? ;-)

If you still have trouble help each other through the comments to this post.

Have a great weekend!
