x^2+y^2=6

解答

x^{2} + y^{2} = 6

(a, b) = (0, 0), r = 6

求解步骤

x^{2} + y^{2} = 6

将

x^{2} + y^{2} = 6

改写为圆标准方程

(x - 0)^{2} + (y - 0)^{2} = (6)^{2}

因此圆的性质是:

(a, b) = (0, 0), r = 6

x^{2} = 16 y

\frac{x ^{2}}{16} + \frac{y ^{2}}{9} = 1

- 9 x^{2} + 4 y^{2} - 36 x - 16 y - 164 = 0

\frac{1}{4} (y + 3) = (x - 2)^{2}

x = - 2 y^{2}
