Problem 246

Is it "from a point P outside e the two tangent" or "from a point P inside c and outside e the two tangent" ?
Ciao.

I presume you are refering to problem #246, so I changed the title (was #245).
Point P is outside the ellipse.
Nothing is said and nothing can be assumed about its position with respect to the circle.

Ops, obviously you're right, it was 246.
Thanks.

Hi, when you say "lattice point", are you considering "points with integer coordinates"?
Thanks.

Can someone confirm if I have the ellipse right.
semi major axis = 7500
semi minor axis = 5590.16...
Thank you.
