Find equations of the osculating circles of the ellipse 9x^2 + 4y^2 = 36 at the points
as far as I understand I need to get T and N at some point on the curve, cross them to get B and use that + a point to write a equasion of plane
i dont know know how to even begin doing this. what do I do if I need to make something parametric? this isn't something I've ever been taught well.
