三角函数是高中数学的重点与难点,很多高中生由于学习观念不正确,解题方法不当,综合能力较差,学习策略不当,犯知识性错误,对三角函数产生了学习困难。为了走出学习三角函数的困境,高中生应从自我做起,掌握正确的学方法;加强数形结合思想的运用;培养数学思维;强化知识理解,掌握使用规律。 Trigonometric function is the key and difficult point of high school mathematics. Many senior high school students have learning difficulties on trigonometric functions because of incorrect learning concepts, improper problem solving methods, poor comprehensive ability, improper learning strategies and knowledge-based errors. In order to get out of the dilemma of learning trigonometric functions, high school students should start from themselves, master the correct method of learning; strengthen the use of mathematical combination of ideas; develop mathematical thinking; strengthen knowledge understanding and master the law of use.
