BOB for Conics

hi everybody, one more unit is done and i was almost forget about the BOB for this unit. T_T .
Anyhow, i just do this BOB briefly.

I think this unit is not really, you just need to know the formula and understand the graph so you could know which formula is parabola, ellipse, or hyperbola.

About the formula, i think some of us already posted it, so i am not going to repeat it. :D

Anyway, Good luck all guys, test on Friday and don't forget your delicious link [which i also almost forgot :-"] ...
