THANK GODzeek said:major axis is 2a semi-major is a
minor axis is 2b semi-minor is b
i used the eccentricity equation to find b.
Same, took way too longRiviet said:I did it the algebraic way as I wasn't sure how to work out the features of the ellipse using the starting equation.
Let z=x+iy.... etc.
I knew there was that geometric method, but wasn't sure of it so just decided to go algebraic.jctaylor said:Probably the easiest way to do this question would be to recognise that the points in the question are the foci, then find that the locus has to pass thru 3i and 10 + 3i
which means the centre would be at 5 + 3i, so the max y has to have Im part of 3i
