The study on conic sections in the lesson. analytic geometry In Grade 4, the curve obtained from the cutting surface with a flat plane or circular cone called "conic sections," a cross-sectional area. Create a circle graph a parabola ellipse hyperbola learn about the characteristics of the graph. The equation for each graph The actual amount that results of the equation are real numbers. The group was wondering if the numbers are still the original form of the conic sections. Graph conic sections and features of the original or not.
