$\bf \cfrac{(x-h)^2}{a^2}+\cfrac{(y-k)^2}{b^2}=1$   any ideas on what "b" might be?

notice the given co-vertices

I am not exactly sure what your asking. I am really struggling with this class... I am not sure what your asking with "b"?

jdoe0001 · Answer

well.. do you know what the vertices are?   and thus what are co-vertices ?

anonymous · Answer

yes i do understand what vertices are.

jdoe0001 · Answer

ok... so we know what the co-vertices and focus are.....

so... what do you think "b" component is?   bear in mind|dw:1414455745747:dw|
