Concepts about parabolas were handled in the previous chapter. This chapter will help the students learn about ellipses and find their equations in normal and nonstandard ways. In this lesson, students study ellipses and derive their equations under certain conditions. The ellipse is defined as the locus of a point in a plane that travels so that the ratio of its distance from a fixed point (focus) in the same plane to its distance from a fixed straight line (directrix) is always constant and less than unity. The ratio of these distances is known as the eccentricity of the ellipse.
The main axis of an ellipse is the line segment that connects the foci of the ellipse to its endpoints on the ellipse. The minor axis is a line segment that goes through the centre of the ellipse and is perpendicular to the major axis. Thus, horizontal ellipse and Vertical ellipse are the two forms of ellipses that may be created.
There is one exercise in Chapter 26 – Ellipse and the chapter contains important concepts like the ellipse equation in its normal form, the tracing of an ellipse, the directrix of the ellipse is also discussed in the chapter. The vertices, major and minor axes, foci, directrices, and the centre are all taught to the students along with their location and applications. The chapter also elaborates on the equations of ordinate, double ordinate, and latus-rectum. Few lesser important topics include the distance between the foci of the ellipse and the minor axis. The equations of the ellipse under varied conditions holds importance in the chapter.
