$$$\frac{\sqrt{2}}{2}\cdot \left\langle -1, 1\right\rangle$$$
사용자 입력
$$$\frac{\sqrt{2}}{2}\cdot \left\langle -1, 1\right\rangle$$$을(를) 계산하세요.
풀이
벡터의 각 성분에 스칼라를 곱하십시오:
$$${\color{Blue}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left\langle -1, 1\right\rangle = \left\langle {\color{Blue}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(-1\right), {\color{Blue}\left(\frac{\sqrt{2}}{2}\right)}\cdot \left(1\right)\right\rangle = \left\langle - \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2}\right\rangle$$$
정답
$$$\frac{\sqrt{2}}{2}\cdot \left\langle -1, 1\right\rangle = \left\langle - \frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2}\right\rangle\approx \left\langle -0.707106781186548, 0.707106781186548\right\rangle$$$A
