Recently, students have generally responded that they cannot start with the problem of the maximum value and range of plane vectors, and now we have sorted out five core methods for your reference:
1.The collinear theorem of plane vectors and its corollary.
2.Fundamental theorem of plane vectors.
3.Multiply the polynomials of the quantitative product of the plane vectors.
4.Planar vector coordinate method.
5.Construct objective functions or equations.
