在近年来的高中数学竞赛与高考试题中,涉及三角函数图象与性质的问题通常与函数的最值、函数的单调性、奇偶性等知识密切相关.在考查过程中通常是与其他函数混合在一起,从而对所学知识进行综合性的考查,由此考查考生对于所学知识的综合应用能力.因此,这就要求考生经常性的对所学知识进行复习、总结,从而达到熟练应用的目的. In recent high school math competitions and high test questions, questions concerning the image and nature of trigonometric functions are often closely related to knowledge of the function’s maximum value, function monotonicity, parity, etc. In the examination process, it is usually mixed with other functions. Together, a comprehensive examination of the learned knowledge is conducted to examine the candidate’s comprehensive application of the knowledge he has learned. Therefore, this requires the examinee to regularly review and summarize the learned knowledge so as to achieve a skilled application. purpose.
