  • 我正在着手修复这个问题

我正在访问这个页面(最好带链接)

https://oi-wiki.org/math/vector/#_17

我发现页面有这样的问题

原公式为:
$\boldsymbol a = \lambda \boldsymbol b$ $\Leftrightarrow$ $\boldsymbol a\cdot \boldsymbol b=|\boldsymbol a||\boldsymbol b|$
显然当$\lambda < 0$时不成立
应更正为:
$\boldsymbol a = \lambda \boldsymbol b$ $\Leftrightarrow$ $|\boldsymbol a\cdot \boldsymbol b|=|\boldsymbol a||\boldsymbol b|$
