反正弦函数教法的探讨

On the Teaching of the Inverse Sine Function

反三角函数的教学,重点应放在反正弦函数,抓住反正弦函数定义的由来,形成鲜明的概念,就容易理解其定义、定义域、值域和性质,并会应用公式进行三角运算。

The attentions of teaching the inverse trigonometric function should be paid to the teaching of the inverse sine function, getting to know the form of defining the inverse sine function to make clear conception. Only in this way the definition, domain and range can be easily comprehended and the triangle formulas can be applied to the operation.
