三角函数是高中数学的重要内容,也是每年高考的必考内容。在高考试题中,三角函数试题一般不会出现较难题,更不会出现难题,因而对大多数学生来说,三角函数试题是高考中的得分点。在解答三角高考题时要善于为发现角和函数运算间的差异,努力运用相关公式,找出差异之间的内在联系,选择恰当的公式,促使差异的合理转化。
Trigonometry is an important part of high school mathematics, and it is also the compulsory part of college entrance examination every year. In the college entrance examination exam questions, trigonometry questions generally do not appear more difficult problems, but will not be a problem, so most students, the trigonometric function test points in the college entrance examination scores. When answering the question of the college entrance examination, you should be good at discovering the difference between the angle and the function. Trying to use the relevant formula to find out the intrinsic relationship between the differences and choosing the appropriate formula to promote the reasonable conversion of the difference.
