Python math.sin()方法 (Python math.sin() method)

math.sin() method is a library method of math module, it is used to get the sine of the number in radians, it accepts a number returns the cosine of the given number in radians.

math.sin()方法是數(shù)學(xué)模塊的庫(kù)方法，用于獲取以弧度為單位的數(shù)字的正弦值，它接受一個(gè)以弧度為單位返回給定數(shù)字的余弦值的數(shù)字。

Note: math.sin() method accepts the only number, if we provide anything else except the number, it returns error TypeError - "TypeError: a float is required".

注意： math.sin()方法接受唯一的數(shù)字，如果我們提供除數(shù)字以外的其他任何內(nèi)容，它將返回錯(cuò)誤TypeError- “ TypeError：需要浮點(diǎn)數(shù)” 。

Syntax of math.sin() method:

math.sin()方法的語(yǔ)法：

math.sin(x)

Parameter(s): x – is the number whose sine to be calculated.

參數(shù)： x –是要計(jì)算其正弦的數(shù)字。

Return value: float – it returns a float value that is the sine value of the number x radians.

返回值： float-它返回一個(gè)浮點(diǎn)值，該值是數(shù)字x弧度的正弦值。

Example:

例：

Input:a = 0.278# function callprint(math.sin(a))Output:0.27443298625778634

Python代碼演示math.sin()方法的示例 (Python code to demonstrate example of math.sin() method)

# python code to demonstrate example of # math.sin() method # importing math module import math# number a = -1 print("sin(",a,") is = ", math.sin(a))a = 0 print("sin(",a,") is = ", math.sin(a))a = 0.278 print("sin(",a,") is = ", math.sin(a))a = 1 print("sin(",a,") is = ", math.sin(a))

Output

輸出量

sin( -1 ) is = -0.8414709848078965 sin( 0 ) is = 0.0 sin( 0.278 ) is = 0.27443298625778634 sin( 1 ) is = 0.8414709848078965

TypeError example

TypeError示例

# python code to demonstrate example of # math.sin() method with an exception# importing math module import math# number a = "2" print("sin(",a,") is = ", math.sin(a))

Output

輸出量

Traceback (most recent call last):File "/home/main.py", line 9, in <module>print("sin(",a,") is = ", math.sin(a)) TypeError: a float is required
