$$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle$$$
该计算器将把向量 $$$\left\langle 0, 3, 4\right\rangle$$$ 与标量 $$$\frac{4}{25}$$$ 相乘，并显示步骤。
您的输入
计算 $$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle$$$。
解答
将向量的每个坐标乘以该标量：
$$${\color{GoldenRod}\left(\frac{4}{25}\right)}\cdot \left\langle 0, 3, 4\right\rangle = \left\langle {\color{GoldenRod}\left(\frac{4}{25}\right)}\cdot \left(0\right), {\color{GoldenRod}\left(\frac{4}{25}\right)}\cdot \left(3\right), {\color{GoldenRod}\left(\frac{4}{25}\right)}\cdot \left(4\right)\right\rangle = \left\langle 0, \frac{12}{25}, \frac{16}{25}\right\rangle$$$
答案
$$$\frac{4}{25}\cdot \left\langle 0, 3, 4\right\rangle = \left\langle 0, \frac{12}{25}, \frac{16}{25}\right\rangle = \left\langle 0, 0.48, 0.64\right\rangle$$$A
