see ill tell u the method
OpenStudy (anonymous):
the hyperbola is of the form x^2/a^2 + y^2/b^2 = 1
OpenStudy (anonymous):
a = 3 as the vertices are at 3,0 and -3,0
OpenStudy (anonymous):
if the angle bw asymptotes is t, the eccentricity e = sec (2t)
OpenStudy (anonymous):
and we know
b^2/a^2 = e^2 - 1

so find b frm this..get it?
OpenStudy (anonymous):
b is 72/25
OpenStudy (anonymous):
get it??????
OpenStudy (amistre64):
that part tends to get me; why would 'b' not be 4?
OpenStudy (anonymous):
yeah i got it i think

what is the actual equation though
OpenStudy (amistre64):
x^2 y^2
--- - ---- = 1 right?
9 b^2
OpenStudy (anonymous):
so there is no b^2?
OpenStudy (amistre64):
im thinking b^2 = 16 .... but i could be wrong
OpenStudy (amistre64):
hims smart about this stuff which makes me doubt my b^2 :)
