| Abstract: | Vector is the new addition in New Curriculum for High School, which has a dual identity. It can satisfy the ＂operational nature＂ to be operated in an algebraic form like characters, and we can also use its geometric significance to undergo conversion in a geometric form. This thesis aims to describe the application of auxiliary vector in solving high school mathematical problems form three aspects. |
