| 摘 要： | 本文利用作者发现总结的＋k（k∈z）和原有的-α与α角三角函数关系两组公式，即可替代原来的五组公式才能解决的求任意角三角函数值，并将原来解决该类问题的步骤简化为两步甚至一步，极大地简化了求任意角三角函数值的问题。

| Abstract: | This article introduces a method by the author and the original trigonometric trigonometric function. it. It also simplifies th making use of two groups of formulas, ＋k （k ∈ z） discovered function relation between -α and α, to solve the free angle This method change the original method： five groups of formulas are all used to do e steps into two, even one step. So the question can be simplified greatly. |
