解決sqrt{L^2+b^2+h^2}=30 |Microsoft數學求解器

$$\sqrt { L ^ { 2 } + b ^ { 2 } + h ^ { 2 } } = 30$$

解 L (復數求解)

$$L=-\sqrt{900-h^{2}-b^{2}}$$

$$L=\sqrt{900-h^{2}-b^{2}}$$

解 b (復數求解)

$$b=-\sqrt{900-h^{2}-L^{2}}$$

$$b=\sqrt{900-h^{2}-L^{2}}$$

解 L

$$L=\sqrt{900-h^{2}-b^{2}}$$

$$L=-\sqrt{900-h^{2}-b^{2}}\text{, }|b|\leq \sqrt{900-h^{2}}\text{ and }|h|\leq 30$$

解 b

$$b=\sqrt{900-h^{2}-L^{2}}$$

$$b=-\sqrt{900-h^{2}-L^{2}}\text{, }|L|\leq \sqrt{900-h^{2}}\text{ and }|h|\leq 30$$
