Tuesday May 19

Since we were only 4 people in class today, including Mr. Max; we only went over the ellipse part of Conics and did not do Hyperbolae yet, but that will be on tomorrow. Homework is 1-10 on Ex. 37 and Acc. Math

Here are our screenshots:









What I think should be noted for these kind of functions is, that the a and b in the formula changes its place in the visualization, according to which one of them is bigger, which is a bit confusing, because everything else in the study of Mathematics seems logical to me, but this ;)

a is always whichever line, from the center to any vertex, is longer!
from one vertex to the opposite one is always 2a or 2b!

I hope that raised the general confusion ;D
