$$$\frac{\sqrt{3}}{3}\cdot \left\langle 1, -1, 1\right\rangle$$$
您的輸入
計算 $$$\frac{\sqrt{3}}{3}\cdot \left\langle 1, -1, 1\right\rangle$$$。
解答
將向量的每個分量乘以該純量：
$$${\color{Chartreuse}\left(\frac{\sqrt{3}}{3}\right)}\cdot \left\langle 1, -1, 1\right\rangle = \left\langle {\color{Chartreuse}\left(\frac{\sqrt{3}}{3}\right)}\cdot \left(1\right), {\color{Chartreuse}\left(\frac{\sqrt{3}}{3}\right)}\cdot \left(-1\right), {\color{Chartreuse}\left(\frac{\sqrt{3}}{3}\right)}\cdot \left(1\right)\right\rangle = \left\langle \frac{\sqrt{3}}{3}, - \frac{\sqrt{3}}{3}, \frac{\sqrt{3}}{3}\right\rangle$$$
答案
$$$\frac{\sqrt{3}}{3}\cdot \left\langle 1, -1, 1\right\rangle = \left\langle \frac{\sqrt{3}}{3}, - \frac{\sqrt{3}}{3}, \frac{\sqrt{3}}{3}\right\rangle\approx \left\langle 0.577350269189626, -0.577350269189626, 0.577350269189626\right\rangle$$$A
