新课标在三角函数章节中注意了知识的连贯性、整体性、统一性、层次性,符合学生的认识特点。对公式的记忆要求降低,不再过多地强调死记硬背,而是注重学生思维能力、解决问题能力以及创新意识的培养。三角函数在传统教学中主要有三个方面的要求:三角恒等变形、三角函数的性质、三角函数的工具作用。由 The new curriculum standard in the trigonometry chapter attention to the continuity of knowledge, integrity, unity, hierarchy, in line with the characteristics of the students’ awareness. Demands on the memory of the formula to reduce, not too much emphasis on rote memorization, but rather focus on student thinking skills, problem solving skills and innovative awareness training. Trigonometric functions in the traditional teaching there are three main requirements: triangular constant deformation, the nature of trigonometric functions, the trigonometric function of the tool role. by
