带有Python示例的math.asin()方法
Pythonmath.asin()方法
math.asin()方法是数学模块的库方法，用于获取反正弦值，它接受介于-1到1之间的数字，并返回给定数字的反正弦值（以弧度为单位）。
注意：math.asin()方法接受-1到1之间的范围内的唯一号码，如果我们提供数超出范围，则返回一个ValueError异常-“ValueError异常：数学领域的错误”，如果我们提供任何其他除外数量，则返回错误类型错误-“TypeError：需要浮点数”。
它的语法math.asin()方法：
math.asin(x)
Parameter(s)：x–是要计算其反正弦值的数字。
返回值：float-它返回一个浮点值，它是数字x的反正弦值。
