Introduction to Python’s math module
Introduction to Python’s math module (Python数学模块简介)
Python’s math module is a built-in library that provides access to a wide range of mathematical functions and constants. This module is an essential tool for carrying out mathematical calculations in Python. The math module provides functions for basic arithmetic operations, such as addition, subtraction, multiplication, and division. It also provides functions for more advanced mathematical operations, such as trigonometric functions, logarithmic functions, and exponential functions.
Basic arithmetic functions
Basic arithmetic functions (基本算术函数)
The math module provides basic arithmetic functions that are essential for carrying out simple calculations. These functions include addition, subtraction, multiplication, and division. Here is an example of how to use these functions:
import math
# addition
a = math.add(2, 3)
# subtraction
b = math.subtract(5, 2)
# multiplication
c = math.multiply(3, 4)
# division
d = math.divide(10, 2)
Trigonometric functions
Trigonometric functions (三角函数)
The math module provides a range of trigonometric functions that are essential for carrying out calculations involving angles. These functions include sine, cosine, tangent, cotangent, secant, and cosecant. Here is an example of how to use these functions:
import math
# sine function
a = math.sin(math.pi/2)
# cosine function
b = math.cos(math.pi/2)
# tangent function
c = math.tan(math.pi/4)
# cotangent function
d = math.cot(math.pi/4)
# secant function
e = math.sec(math.pi/3)
# cosecant function
f = math.csc(math.pi/6)
Logarithmic functions
Logarithmic functions (对数函数)
The math module provides logarithmic functions that are essential for carrying out calculations involving logarithms. These functions include the natural logarithm (log base e), the common logarithm (log base 10), and the logarithm with an arbitrary base. Here is an example of how to use these functions:
import math
# natural logarithm
a = math.log(2.718)
# common logarithm
b = math.log10(100)
# logarithm with an arbitrary base
c = math.log(16, 2)
Exponential functions
Exponential functions (指数函数)
The math module provides exponential functions that are essential for carrying out calculations involving exponents. These functions include the exponential function (e raised to the power of x), and the power function (x raised to the power of y). Here is an example of how to use these functions:
import math
# exponential function
a = math.exp(2)
# power function
b = math.pow(2, 3)
