线性代数示例

x^{2} + y^{2} = 40

$x^{2} + y^{2} = 40$ ,

x^{2} - y^{2} = - 32

$x^{2} - y^{2} = - 32$

解题步骤 1

方程组不是线性方程组。

x^{2} + y^{2} = 40, x^{2} - y^{2} = - 32

$x^{2} + y^{2} = 40, x^{2} - y^{2} = - 32$

⎡ ⎢ ⎣ \begin{matrix} x^{2} & \frac{1}{2} \sqrt{π} & \int x d x \end{matrix} ⎤ ⎥ ⎦

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
