向量是高中数学中工具性较强的知识点,它区别于我们以前所学的数量,不仅有大小而且又有方向,因此在使用向量时要非常谨慎,又加之向量中一些特殊情况的存在常常要求问题要分类思考,这在一定程度上使得我们在解题时经常犯错,造成不必要的失分.以下给出了向量的常见错误,希望对读者以后的学习有所启示. Vector is a highly instructive point in high school math. It differs from what we have learned before, not only in size but also in direction. Therefore, be very cautious when using vectors, together with the existence of special cases in vectors To ask questions to classify thinking, which to some extent makes us often make mistakes in solving problems, resulting in unnecessary loss points. The following gives the common mistakes of vectors, hoping to enlighten the readers after the study.
