$$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle$$$
사용자 입력
$$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle$$$을(를) 계산하세요.
풀이
벡터의 각 성분에 스칼라를 곱하십시오:
$$${\color{DeepPink}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left\langle 3, 1\right\rangle = \left\langle {\color{DeepPink}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left(3\right), {\color{DeepPink}\left(\frac{\sqrt{10}}{10}\right)}\cdot \left(1\right)\right\rangle = \left\langle \frac{3 \sqrt{10}}{10}, \frac{\sqrt{10}}{10}\right\rangle$$$
정답
$$$\frac{\sqrt{10}}{10}\cdot \left\langle 3, 1\right\rangle = \left\langle \frac{3 \sqrt{10}}{10}, \frac{\sqrt{10}}{10}\right\rangle\approx \left\langle 0.948683298050514, 0.316227766016838\right\rangle$$$A
