Python math.sinh()方法 (Python math.sinh() method)

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

math.sinh()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正弦值，它接受一个数字并返回双曲正弦值。

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

注意： math.sinh()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.sinh() method:

math.sinh()方法的语法：

    math.sinh(x)

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

参数： x –是要计算其双曲正弦值的数字。

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

返回值： float-它返回一个浮点值，它是数字x的双曲正弦值。

Example:

例：

    Input:
x = 1.5
# function call
print(math.sinh(x))
Output:
2.1292794550948173

Python代码演示math.sinh()方法的示例 (Python code to demonstrate example of math.sinh() method)

# Python code to demonstrate example of 
# math.sinh() method
# importing math module
import math 
# number 
x = -10
print("math.sinh(",x,"): ", math.sinh(x))
x = 0
print("math.sinh(",x,"): ", math.sinh(x))
x = 1.5
print("math.sinh(",x,"): ", math.sinh(x))
x = 5
print("math.sinh(",x,"): ", math.sinh(x))
x = 15.45
print("math.sinh(",x,"): ", math.sinh(x))
