MAC 1114 Trigonometry Chapter 9 notes Section 9.1 The Ellipse The four conic sections Conics: From General Form, To Identify Conics One squared term: Parabola Two squared term: same sign & same coefficient: Circle same sign & different coefficient: Ellipse different signs (number value not important): Hyperbola xy term Hyperbola Circles: General Form: Ax 2 + By 2 + Cx + Dy + E = 0 (where A & B are the same coefficient; A = B) Standard Form: (x-h) 2 + (y-k) 2 = r 2 or + = 1 Center: (h, k) radius: A circle is a special type of ellipse, where the major axis and the minor axis are equal. To graph a circle find the exterior points by using the center and the radius.
