Hi Mrs. Corricelli,
for #27-30 on the chapter 10 review I’m having a hard time figuring out how you know which one is a and which is b. for #s 27-29 asquared is below the (y-k), but for 30 it is below the (a-h). Does a always have to be the larger value? i don’t know how you tell by looking at an equation if the major axis is vertical or horizontal.
Sarah-
In the beginning of the chapter, 10.3 i believe, it said a is always larger. However, this does not mean a is always under (x-h) or always under (y-k). It changes. If a is under (x-h), the major axis is horizontal. I
sorry that last comment wasnt done…
if a is under the (y-k) the major axis is vertical.
look at the table on page 743, it helps sort out the major ideas involving ellipses
Yes! That makes so much more sense! Thanks!
Hey! 2 questions in # 33, (the foci and asymptote equations were given and we were trying to but it into standard form): FIRST, the answer packet says that from the given information, you can go straight to (b/a)=2. Does anyone understand why? I was looking at it for a while so I must be missing something. SECOND, shouldn’t the answer at the end have a fraction in the denominator for standard form? I thought having a coefficient in the numerator was illegal. Ok, I think that’s all for now. Thanks guys!
we said today in class that when given the general form of a conic that the graph is a circle when AC=0, an ellipse when AC is between 0 and 1, a parabola if AC=1, and a hyperbola when AC is greater than one, but the book says that it is a circle if A=C, a parabola if AC=0, an ellipse if AC>0, and a hyperbola if AC<0. can someone help to differentiate this?
