三角函数是高考的主要内容之一,包括三角函数定义、诱导公式,三角函数的图象与性质和正、余弦定理,其中,学生学起来比较吃力的是三角函数的图象和性质部分,这部分内容主要包括函数图象的平移、函数最大最小值的求法,函数单调区间的确定,本文就这些考点进行学法分析。 Trigonometric function is one of the main contents of the college entrance examination, including the definition of trigonometric functions, the induction formula, trigonometric function of the image and nature and cosine theorem, of which students learn more difficult is the triangular function of the image and nature of this part The main contents include the translation of the function image, the maximum and minimum function of the function, the determination of the monotonous range of the function.
