{l}{x^2+y^2leq4}{xygeq0} সমাধান কৰক

$$\left\{ \begin{array} { l } { x ^ { 2 } + y ^ { 2 } \leq 4 } \\ { x y \geq 0 } \end{array} \right.$$

x-ৰ বাবে সমাধান কৰক

$$\left\{\begin{matrix}x\in \begin{bmatrix}-\sqrt{4-y^{2}},0\end{bmatrix}\text{, }&y\geq -2\text{ and }y\leq 0\\x\in \begin{bmatrix}0,\sqrt{4-y^{2}}\end{bmatrix}\text{, }&y\geq 0\text{ and }y\leq 2\end{matrix}\right.$$

y-ৰ বাবে সমাধান কৰক

$$\left\{\begin{matrix}y\in \begin{bmatrix}-\sqrt{4-x^{2}},0\end{bmatrix}\text{, }&x\geq -2\text{ and }x\leq 0\\y\in \begin{bmatrix}0,\sqrt{4-x^{2}}\end{bmatrix}\text{, }&x\geq 0\text{ and }x\leq 2\end{matrix}\right.$$
