向量是建立在一种新的运算体系下的产物,与传统的数的运算有着本质的区别.纵观近3年来的高考,对向量的考查力度在逐年加大,而且注重向量的知识性与工具性的考查,其中作为知识性考查,要求变形技巧强,有时难度颇大,成了学生学习的一个难点,但它对学生数学素养、
Vectors are products based on a new computing system, and are fundamentally different from traditional numbers. Over the past three years of college entrance examination, the examination of vectors has been increasing year by year, and the importance of vectors has been emphasized. Instrumental examinations, which, as a test of knowledge, require strong deformation skills and sometimes great difficulty, have become a difficulty for students to learn, but it is for students’ mathematics literacy,
