How can I find a coordinate of ellipse? and make it into a excel table
This is a equation for ellipse that I made I'd like to get a coordinate of points on this ellipse x coordinate starts from -4.9 and increase by 0.1 How can I get y coordinate and make x a...
Did you get anywhere with this?
I think the answer to your question is 'with difficulty'. It requires formulating and solving a quadratic equation in y and the formula is not well behaved near x=5. A better curve can be obtained by using the polar coordinate ϑ as a parameter and calculating the radius r and, from that, the cartesian coordinates (x,y) .
