BOB on Conics

Heeey everybody, sorry to say that this will be short and sweet because I've got loads to do tonight unfortunately :<

On with my BOB!
Honestly, this unit sounded intimidating, but in the end, it really wasn't at all! After I got past getting the hang of the geometry, I actually started to enjoy it... (Except for sketching graphs, I always did despise doing that.) :]
So now that I pretty much get the jist of all the geometry involving parabolas, ellipses and hyperbolas, I think I'll do well in that aspect.
Applying them to "realistic" situations won't be my cup of coffee (gonna have to load up on this tmrw huhu). I'm sure with a little more practice I'll have a full understanding of taking pieces of information and constructing the proper equation for it, but waugh! In due time...

What I found interesting was that when you take a line and "spin" it, you end up with two cones, and from there you can derive the parabola, ellipse, and hyperbola! I'd describe/post images of this, but Jessi's scribe post on Conics had very good ones already :].

Now, onto the guidelines which I shamefully hardly ever follow...
  • Get at least some sleep! Actually, sleep immediately after you study, you'll remember your stuff better!
  • Eat breakfast, brain food = awesome because you don't want to hear your stomach during the test and neither do we lol.
  • Take your time, don't rush!
  • Keep in mind the equations for vertical/horizontal parabolas, ellipses, and hyperbolas!
  • Look at these equations and see the geometry! Remember, "codes!"
  • a^2 + b^2 = c^2!
  • Be able to take very little given information and build upon them to end up with an equation that will help you out big time!
Anywhoots, I think that's enough brain juice spillage for me. Onto studying!
To everyone who's going on that Kenora trip tmrw... Bye. >_> Just kidding, have fun!
To everyone else, good luck on the test tmrw! :D
