人教版《普通高中课程标准试验教科书B版·数学·必修4》给出的诱导公式相比于旧教材作了较大调整,必然会影响到该内容教学的各方面。我们在研究教材的基础上对诱导公式进一步整合,取得了良好的教学效果。
The induced formula given by the People’s Education Press “General High School Curriculum Standards Test Textbook B Edition·Mathematics·Compulsory 4” has been greatly adjusted compared to the old textbooks, and will inevitably affect all aspects of the content teaching. We further integrated the induction formula on the basis of research materials and achieved good teaching results.
