焦点 (x^2)/(45)-(y^2)/(360)=1

解答

焦点

\frac{x ^{2}}{45} - \frac{y ^{2}}{360} = 1

(95, 0), (- 95, 0)

求解步骤

(h + c, k), (h - c, k)

计算双曲线性质

\frac{x ^{2}}{45} - \frac{y ^{2}}{360} = 1 :

左右开口双曲线，

(h, k) = (0, 0), a = 35, b = 610

(0 + c, 0), (0 - c, 0)

计算

c :

c = (35)^{2} + (610)^{2} : 95

(0 + 95, 0), (0 - 95, 0)

整理后得

(95, 0), (- 95, 0)
