Charlie.

Ok, so we didn't have any aleks due this week.
BUT, we did do stuff for math this week.
we learned chapter 6.
one thing we did was the eclipses & stuff like that.
the formula is: x^2/a + y^2/b = 1
to do this we have to find the major axis, the minor axis, the major length, the minor length, the vertex, other, and the focus.

EXAMPLE:
x^2/4 + y^2/16 = 1
Major --> y
Minor --> x
Major Length --> 8
Minor Length --> 4
Vertex --> (0, 4) (0, -4)
Other --> (2, 0) (-2, 0)
Focus --> (0, 2squarerootof3) (0, -2squarerootof3)
