最值问题是中学数学的一个重要课题,它贯穿在中学数学的各个分支中。由于三角函数的特殊性质,因而三角函数的最值问题也灵活多样,成为考试、检查命题的一个热点。三角函数是一种重要的函数,三角函数的最值问题包括了对三角函数的概念、图像、性质及诱导公式、同角三角函数间基本关系式、两角和差以及倍角公式的考查,是函数思想的具体体现,有广泛的实际应用,一直是高考命题的热点。
The most value problem is an important subject in high school mathematics, which runs through all branches of high school mathematics. Due to the special nature of trigonometric functions, the maximum value of trigonometric functions is also flexible and diverse, becoming a hot spot for examination and examination of propositions. The trigonometric function is an important function. The most significant problem of the trigonometric function includes the concept, image, property and induction of the trigonometric function, the basic relation between the trigonometric functions, the two angles and the difference and the multiplication angle formula. The concrete manifestation of the function thought, has a wide range of practical applications, has been the hot topic of college entrance examination.
