I'm taking summer lessons next year preperations. I started a
new topic(lesson) called Conics. As I know every beginning has a
start . The question :: Determine the equation of the conic
C(F,d,e).Determine the nature of C(F,d,e) and its different
elements. Equation of directrix : x-1= >0 My work is the
following : I ploted the given focus(3,1) and graphed the
directrix x=1,knowing the e = c/a = sqrt(2)/2 --> c =sqrt2 & a
=2 .But since 0<e<1 - so this is an Ellips(correct?) The length
of the major axis is 2a = 2(2)=4 ... The equation is : IS MY
WORK CORRECT ? MISSING SOMETHING? - Thanks in advance-
