三角函数是高中数学中重要的内容,是近几年来高考的热点,同时也是难点.数学学习强调经历学习过程,注重学习的探究与合作,注重学习思想与方法的渗透.一题多解能够很好地体现学习过程中的自主探究能力、灵活驾驭教材的能力和对所学知识融会贯通的能力,而且有利于培养思维广阔性、灵活性、敏捷性,使数学素养进一步得到提升.下面给出笔者对一道习题的多种解法.题目若5cosx+12sinx=13,则tanx
Trigonometric function is an important part of high school mathematics, which is a hot spot and a difficult point in college entrance examination in recent years.Mathematical learning emphasizes the process of learning, focusing on learning to explore and cooperation, focusing on the penetration of learning ideas and methods. Good reflect the learning process of self-exploration ability, the ability to flexibly manipulate teaching materials and knowledge of the ability to get through, but also conducive to the development of broad thinking, flexibility, agility, so that mathematical literacy was further improved.The following is given by the author A variety of solutions to a problem. Problem if 5cosx + 12sinx = 13, the tanx
