三角函数是高中函数内容中的重点之一,而三角函数中两角和与差的余弦、正弦和正切公式是主要考查内容,学生一般对余弦和正弦的理解掌握比较深刻,而在解题中不善于利用正切函数。本文以正切函数运用为主,展开探讨。
Trigonometric function is one of the key points in the content of high school function. The cosine, sine and tangent formulas of two corners and difference in trigonometric function are the main contents of examination. Students generally understand the cosine and sine more profoundly, Not good at using tangent function. In this paper, the main function of the tangent function, to explore.
