Reflection #7
This week was a hard to handle week. The week started with a test..if that doesn’t say “beware of the week to follow” I don’t know what does. To speak on the test, I wanna say that I was completely confident Monday morning going into school that I knew the test material and I would totally fly through the test. I mean, we had a quiz on each separate section that would be on the test, and I studied for each quiz and did fairly well. Plus I had the weekend to study extra for the test. I can’t say I really feel like I did badly. I was disappointed that there were a few questions I got mixed up on but I am proud to say that there was only one question that I did not answer.
Now for the basics that each blog entry needs,
I most definitely am confident in my knowledge of the steps necessary for graphing a conic equation.
STEPS FOR SKETCHING CONICS
Determine shape
Find center
Mark Major axis
Mark Minor axis
Mark Other intercepts
Mark Focus (or Foci)
Decipher Asymptotes
Mark Vertex
Complete Sketch
What I am not confident in is my knowledge of how to decipher between a circle equation and an elliptical equation. I kind of figure that I could find a way to guess between the two or I could find a way to solve the problem and when I go to sketch the conic it will appear as the shape. However I doubt this is an effective way to go about completing the Chapter 6 test. So notes on how to distinguish between the two would be great!

The equation of a circle does not have fractions
ReplyDelete(x+h)^2+(y+k)^2=r^2
However, the equation of an ellipse has a fraction
*unless the denominator is 1.
x^2/4+y^2=1
Like alaina said a circles equation has no fractions
ReplyDelete(x+h)^2+(y+k)^2=r^2
and an ellipse is a fraction...but an ellipse can have a denominator of one which would still make it a fraction.
