(1/2)^2+x^2=1

解

(\frac{1}{2})^{2} + x^{2} = 1

x = \frac{3}{2}, x = - \frac{3}{2}

十進法表記

x = 0.86602 \dots, x = - 0.86602 \dots

解答ステップ

(\frac{1}{2})^{2} + x^{2} = 1

拡張

(\frac{1}{2})^{2} + x^{2} : \frac{1}{4} + x^{2}

\frac{1}{4} + x^{2} = 1

\frac{1}{4}

を右側に移動します

x^{2} = 1 - \frac{1}{4}

簡素化

1 - \frac{1}{4} : \frac{3}{4}

x^{2} = f (a)

の場合, 解は

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

x = \frac{3}{4}, x = - \frac{3}{4}

\frac{3}{4} = \frac{3}{2}

- \frac{3}{4} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}
