(-(sqrt(11))/4)^2+y^2=1

解答

(- \frac{11}{4})^{2} + y^{2} = 1

解答

y = \frac{5}{4}, y = - \frac{5}{4}

+1

十进制

y = 0.55901 \dots, y = - 0.55901 \dots

求解步骤

(- \frac{11}{4})^{2} + y^{2} = 1

展开

(- \frac{11}{4})^{2} + y^{2} : \frac{11}{16} + y^{2}

\frac{11}{16} + y^{2} = 1

将

\frac{11}{16}

到右边

y^{2} = 1 - \frac{11}{16}

化简

1 - \frac{11}{16} : \frac{5}{16}

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

y = \frac{5}{16}, y = - \frac{5}{16}

\frac{5}{16} = \frac{5}{4}

- \frac{5}{16} = - \frac{5}{4}

y = \frac{5}{4}, y = - \frac{5}{4}
