Noun. 1. ellipse-a closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it; the sums of the distances from the foci to any point on an ellipse is constant. oval. conic, conic section - (geometry) a curve generated by the intersection of a plane and a circular cone.
A tangent is a line that just touches a curve at one point, without cutting across it. Here is a tangent to an ellipse: Here is a cool thing: the tangent line has equal angles with the two lines going to each focus! Try bringing the two focus points together (so the ellipse is a circle) ... what do you notice? Section of a Cone. You can also get an ellipse when you slice through a cone (but not too steep a slice, or you get a parabola or hyperbola). In fact the ellipse is a conic section (a section of a cone) with an eccentricity between 0 and 1. Equation By placing an ellipse on an x-y graph (with its major axis on the x-axis and minor axis on the y-axis), the equation of the curve is:
