y^2=1-y^2

解答

y^{2} = 1 - y^{2}

解答

y = \frac{1}{2}, y = - \frac{1}{2}

+1

十进制

y = 0.70710 \dots, y = - 0.70710 \dots

求解步骤

y^{2} = 1 - y^{2}

将

y^{2}

para o lado esquerdo

2 y^{2} = 1

两边除以

2

y^{2} = \frac{1}{2}

对于

x^{2} = f (a)

解为

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

y = \frac{1}{2}, y = - \frac{1}{2}

\frac{1}{2} = \frac{1}{2}

- \frac{1}{2} = - \frac{1}{2}

y = \frac{1}{2}, y = - \frac{1}{2}
