Anybody?

jdoe0001 · Answer

hmm dunno what's meant by "rotation of the axes", I can tell is an ellipse pretty much

anonymous · Answer

Well I learned was that you have to find an angle form using $$\cot 2$$

hmmm.... don't think I've covered that

anonymous · Answer

Well our professor told us to start with$$\frac{ a-c }{ b }$$then that equals to cot 2 theta somehow

hmmm dunno that one :(

Its ok I already missed the homework deadline
