Teaching Research On The Trigonometric Representation Of Complex Numbers In Senior High School

Trigonometric representation of complex numbers highlights the connection between Complex numbers and Triangle function,Vector,Geometry,has a very important position in the Complex numbers knowledge system and even the whole mathematics,but ?High school mathematics curriculum standard(2017 edition)?arranged it for the compulsory content,plus complex content small in high school,teachers and students are not pay attention to,no in-depth teaching.According to the above situation,based on the 2019 edition,this paper designed the school-based curriculum integrating Trigonometric representation of complex numbers of mathematical culture.First,it analyzes the importance of plural triangle teaching through literature research,the school-based curriculum design improves students 'Complex numbers knowledge system in high school,and adds students' Complex numbers history,and improves students ' interest in plural.Then the feasibility of complex number triangle teaching is analyzed through classroom observation,individual interviews and heterogeneous teaching experiment.According to the above research,it is found that the history of mathematics is integrated into the teaching process of complex triangle forms,so that students can have deeply understood the ups and turns of complex numbers,show the cultural value of mathematics to students,and improve students ' understanding and understanding of Trigonometric representation of complex numbers.The use of school-based curriculum also provides another teaching platform for compulsory learning content.
