$$$\frac{1}{5}\cdot \left\langle 3, 4\right\rangle$$$
该计算器将把向量 $$$\left\langle 3, 4\right\rangle$$$ 与标量 $$$\frac{1}{5}$$$ 相乘，并显示步骤。
您的输入
计算 $$$\frac{1}{5}\cdot \left\langle 3, 4\right\rangle$$$。
解答
将向量的每个坐标乘以该标量：
$$${\color{SaddleBrown}\left(\frac{1}{5}\right)}\cdot \left\langle 3, 4\right\rangle = \left\langle {\color{SaddleBrown}\left(\frac{1}{5}\right)}\cdot \left(3\right), {\color{SaddleBrown}\left(\frac{1}{5}\right)}\cdot \left(4\right)\right\rangle = \left\langle \frac{3}{5}, \frac{4}{5}\right\rangle$$$
答案
$$$\frac{1}{5}\cdot \left\langle 3, 4\right\rangle = \left\langle \frac{3}{5}, \frac{4}{5}\right\rangle = \left\langle 0.6, 0.8\right\rangle$$$A
