平面向量是高中数学中的一个重要工具,它以其独特的数形结合和坐标运算成为衔接代数与几何的最佳纽带,利用平面向量可以方便地解决很多数学问题,因此在实际解题中平面向量常常被当作工具与其他知识进行交汇使用。如平面向量可以与方程、函数、数列、不等式、三角函数、解三角形、平面几何、立体几何、平面解析几何、概率、导数等知识进行交汇,在这些问题中,平面向量大多是作为工具构造一种计算关系,然后再依据相关知识进行计算。下面我们举例说明各类交汇问题的特点及解决办法。
Plane vector is an important tool in high school mathematics. Because of its unique combination of numbers and coordinates, plane vector is the best link between concatenation algebra and geometry. Plane vectors can easily solve many mathematical problems. Therefore, Vectors are often used as tools to interface with other knowledge. For example, plane vectors can be intersected with equations, functions, sequences, inequalities, trigonometric functions, solution triangles, plane geometry, solid geometry, plane analysis geometry, probability, derivative, etc. In these problems, plane vectors are mostly constructed as tools Calculate the relationship, and then calculate based on the relevant knowledge. Below we illustrate the characteristics of various types of intersection problems and solutions.
