摘要:
本文以解决一个含反三角函数的复杂定积分问题为切入点,从换元法、奇偶性分析以及反三角函数关系式的应用等多个视角展开深入研究。通过对每种视角解题方法的详细阐述,不仅有效解决了该定积分问题,同时也凸显出高等数学中积分技巧的多样性和灵活性。进一步地,本文探讨了这些视角解题方法在高等数学教学中的应用价值,并针对每种方法提出了具体教学启示,旨在为定积分知识的教学提供新的视角和策略,帮助教师更高效地引导学生理解和掌握复杂的积分技巧。This paper takes the solution of a complex definite integral involving inverse trigonometric functions as the entry point and conducts an in-depth study from multiple perspectives, including the application of substitution methods, analysis of odd-even properties, and utilization of inverse trigonometric function relationships. By elaborating on the detailed steps and logical reasoning of each perspective’s problem-solving approach, the paper not only effectively addresses the definite integral problem but also highlights the diversity and flexibility of integral techniques in advanced mathematics. Furthermore, the paper explores the pedagogical value of these problem-solving methods in the teaching of advanced mathematics and offers specific teaching insights for each method. It aims to provide new perspectives and strategies for the instruction of definite integrals, thereby assisting educators in more efficiently guiding students to understand and master complex integration techniques.
