Difference between a hyperbola and ellipse

This was a comment that I made regarding Joyce's BOB post.



Joyce,

After reading your BOB post, I can see that you are having troubles with the differences between the standard form of ellipse and hyperbola. They are very similar and sometimes hard to distinguish because Mr. K might algebraically massage them and make them look harder than they actually are. I think that there is only one difference between them. On a ellipse the terms are suppose to have the same signs. On the other hand, on the hyperbola the terms should have opposite signs. To further enhance your learning about this you can check this out: http://people.richland.edu/james/lecture/m116/conics/conics.html

Logarithms and Their Laws

This is comment on Joyce's post. Her post was also about logarithmic laws and its application. I must say that I'm loving how they are including images when they are trying to explain a certain concept. It is just easier to learn compare to a scribe post with just plain text.

Joyce,

I must say that it was a really long scribe post, but it was very well done. Like i said on Kristina's scribe post, I like how you inserted an image so that your readers can easily link to what you are saying. It saves them lots of time and most of all makes them learn visually. I like to consider myself as a visual learner so this post really helped me relearn all this laws.
