Python中带有示例的math.sin()方法
Pythonmath.sin()方法
math.sin()方法是数学模块的一种库方法，用于获取以弧度为单位的数字的正弦，它接受一个以弧度为单位返回给定数字的余弦的数字。
注意：math.sin()方法接受的唯一的号码，如果我们提供任何其他除外数量，则返回错误类型错误-“类型错误：需要浮动”。
它的语法math.sin()方法：
math.sin(x)
Parameter(s)：x–是要计算其正弦的数字。
返回值：float-返回一个浮点值，该值是数字x弧度的正弦值。
示例
Input:
a = 0.278
#函数调用
print(math.sin(a))
