Python math.cosh()方法 (Python math.cosh() method)math.cosh() method is a library method of math module, it is used to get the hyperbolic cosine of given number in radians, it accepts a number and returns hyperbolic cosine.
math.cosh()方法是数学模块的库方法,用于获取以弧度为单位的给定数字的双曲余弦值,它接受一个数字并返回双曲余弦值。
Note: math.cosh() method accepts only numbers, if we provide anything else except the number, it returns error TypeError – "TypeError: a float is required".
注意: math.cosh()方法仅接受数字,如果我们提供除数字以外的任何其他内容,它将返回错误TypeError – “ TypeError:需要浮点数” 。
Syntax of math.cosh() method:
math.cosh()方法的语法:
math.cosh(x)Parameter(s): x – is the number whose hyperbolic cosine to be calculated.
参数: x –是要计算其双曲余弦的数字。
Return value: float – it returns a float value that is the hyperbolic cosine value of the number x.
返回值: float-返回一个浮点值,该值是数字x的双曲余弦值。
Example:
例:
Input: x = 1.5 # function call print(math.cosh(x)) Output: 2.352409615243247 Python代码演示math.cosh()方法的示例 (Python code to demonstrate example of math.cosh() method) # Python code to demonstrate example of # math.cosh() method# importing math moduleimport math # number x = -10print("math.cosh(",x,"): ", math.cosh(x))x = 0print("math.cosh(",x,"): ", math.cosh(x))x = 1.5print("math.cosh(",x,"): ", math.cosh(x))x = 5print("math.cosh(",x,"): ", math.cosh(x))x = 15.45print("math.cosh(",x,"): ", math.cosh(x))Output
