$$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle$$$
您的輸入
計算 $$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle$$$。
解答
將向量的每個分量乘以該純量：
$$${\color{GoldenRod}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left\langle 3, 1\right\rangle = \left\langle {\color{GoldenRod}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left(3\right), {\color{GoldenRod}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left(1\right)\right\rangle = \left\langle \frac{3 \sqrt{10}}{10}, \frac{\sqrt{10}}{10}\right\rangle$$$
答案
$$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle = \left\langle \frac{3 \sqrt{10}}{10}, \frac{\sqrt{10}}{10}\right\rangle\approx \left\langle 0.948683298050514, 0.316227766016838\right\rangle$$$A
