$$$\frac{\sqrt{6}}{6}\cdot \left\langle 1, 2, 1\right\rangle$$$
您的輸入
計算 $$$\frac{\sqrt{6}}{6}\cdot \left\langle 1, 2, 1\right\rangle$$$。
解答
將向量的每個分量乘以該純量：
$$${\color{SaddleBrown}\left(\frac{\sqrt{6}}{6}\right)}\cdot \left\langle 1, 2, 1\right\rangle = \left\langle {\color{SaddleBrown}\left(\frac{\sqrt{6}}{6}\right)}\cdot \left(1\right), {\color{SaddleBrown}\left(\frac{\sqrt{6}}{6}\right)}\cdot \left(2\right), {\color{SaddleBrown}\left(\frac{\sqrt{6}}{6}\right)}\cdot \left(1\right)\right\rangle = \left\langle \frac{\sqrt{6}}{6}, \frac{\sqrt{6}}{3}, \frac{\sqrt{6}}{6}\right\rangle$$$
答案
$$$\frac{\sqrt{6}}{6}\cdot \left\langle 1, 2, 1\right\rangle = \left\langle \frac{\sqrt{6}}{6}, \frac{\sqrt{6}}{3}, \frac{\sqrt{6}}{6}\right\rangle\approx \left\langle 0.408248290463863, 0.816496580927726, 0.408248290463863\right\rangle$$$A
