Python双曲函数/方法 (Python Hyperbolic functions/methods)

In python programming language, there are some of the built-in functions which are defined in math module – they can be used for hyperbolic calculations (these functions are analogs of trigonometric functions those are based on hyperbolas instead of circles.), python has following Hyperbolic functions, which are used to various purposes.

在python编程语言中 ， 数学模块中定义了一些内置函数-它们可用于双曲线计算(这些函数是基于双曲线而不是圆的三角函数的类似物。)，python具有以下功能双曲函数 ，用于多种用途。

Python中的双曲函数列表 (List of hyperbolic functions in Python)

Python代码演示所有双曲函数的示例 (Python code to demonstrate example of all hyperbolic functions)

# Python code to demonstrate example of
# all hyperbolic functions
# importing math module
import math
# number
x = 1.25
# math.acosh()
print("math.acosh(",x,"): ", math.acosh(x))
# math.asinh()
print("math.asinh(",x,"): ", math.asinh(x))
# math.atanh()
x = 0.56
print("math.atanh(",x,"): ", math.atanh(x))
# math.cosh()
print("math.cosh (",x,"): ", math.cosh(x))
x = 1.25
# math.sinh()
print("math.sinh (",x,"): ", math.sinh(x))
# math.tanh()
print("math.tanh (",x,"): ", math.tanh(x))

Output

双曲函数的异常 (Exceptions with hyperbolic functions)

There are two types of exceptions occur,

有两种类型的异常发生，

• ValueError

  ValueError

  When we provide an invalid value (number), this exception occurs.

  当我们提供无效的值(数字)时，将发生此异常。

• TypeError

  TypeError

  When we provide a different type of values except a number, this exception occurs.

  当我们提供数字以外的其他类型的值时，会发生此异常。

ValueError example

ValueError示例

# Python code to demonstrate example of
# math.atanh() method with exception
# importing math module
import math
# number
x = -1
print("math.atanh(",x,"): ", math.atanh(x))

Output

输出量

Traceback (most recent call last):
File "/home/main.py", line 9, in <odule>
print("math.atanh(",x,"): ", math.atanh(x))
ValueError: math domain error

TypeError example

TypeError示例

# Python code to demonstrate example of
# math.atanh() method with exception
