We already know from Section 1.8 that the graph of the equation 2 2 2 x y r is a circle. We will find equations for each of the other conic sections by analyzing their geometric properties. The conic sections have interesting properties that make them useful for many real-world ...
We obtain similar equations for parabolas opening to the right or to the left (Figure 10.4 and Table 10.1). 2 Focus (0, –p ) x – 4py TABLE 10.1 Standard-form equations for parabolas with vertices at the origin sp 7 0d FIGURE 10.3 The parabola Equation Focus Directrix Axis Opens 2 ...
