Python math functions and modules

$Python math functions and modules$

Hi guys. Welcome to another session of python programming. If you are new here please do checkout our previous on python. Also check out our YouTube channel to get the full tutorial on this article.

In this session we are going to see the different math functions and modules in python.

Python has a variety of default functions which do not require any import module. Some of this predefined functions are: input(), int(), float(), type() and many others.

The syntax for this python math module and functions is given below

$Python math functions and modules$

Python math module

Python has an already default module known as math module which has a list of predefined functions to do mathematical calculations. To first work with this math module, we need an import statement:

import math

Below is a list of table showing some math’s function

pow	math.pow(base,exp)	This function returns base raised to power exp. Error occurs if (base=0 and exp<=0) or (base<0 and exp is not integer).	math.pow(8,2) gives 64
ceil	math.cell(num)	This function returns next integer value.	math.ceil(1.3) gives 2.0 math.ceil(-1.3) gives -1.0
floor	math.floor(num)	This function returns previous integer value.	math.floor(1.3) gives 1.0 math.ceil(-5.-3) gives -4
sqrt	math.sqrt(num)	This function returns the square root of a number. If number is less than 0, error will be shown.	math.sqrt(64.0) gives 8.0.

log10	math.log10(num)	log10() function returns the base 10 logarithm for num. Error occurs if num <=0.	math.log10(1.0) give base 10 logarithm for 1.0.
sin	math.sin(arg)	sin() function returns the sine of arg. The value of arg must be in radians	math.sin(val) (val is a number)
cos	math.cos(arg)	cos() function returns the cosine of arg. The value of arg must be in radians	math.cos(val) (val is a number)
tan	math.tan(arg)	tan() function returns the tangent of arg. The value of arg must be in radians	math.tan(val) (val is a number)
degrees	math.degrees(x)	degrees() converts angle x from radians to degrees.	math.degrees(478) would give 27,387.38
radians	math.radians(x)	radians() converts angle x from degrees to radians.	math.radians(14) would give. 0.244346

Pi has the mathematical value pi=3.141592.
Mathematical e has the mathematical value e=2.718281
The function in python are used directly

Below are some mathematical functions when they are executed in a shell

We have now come to the end of this session. Hope enjoyed this article. Don’t forget to check out the articles on the programming languages guys. Happy coding

Introduction to flask

Hello. Welcome to another session on this platform. If you are new here, please do checkout our previous articles on python programming language and stay excited on this session because we are entering into one of python’s web-based application called flask. In this article, we are going to see the following What is flask Prequistes Installation of flask in python Some of flask template engine. What is flask? Flask is one of python-based framework which is used to create web applications. Flight is a very light web framework. During installation, flask comes with pre-installed modules and functions which are used to backup your own web applications. Flask is very easy to understand and perfect go-to for beginners and with flask, a web server can run in less than 3 lines of code. Prequistes Before learning flask, we recommend the reader to have a basic mastery of python concepts. Installation of flask Before installing flask, we have to checked if python has been installed or. If n...

How to generate random numbers using NumP1

Hello. Welcome to another edition on this platform. For more better understanding, do checkout our YouTube channel to get the video tutorial. In this article of today, we are going to see how to generate random numbers using any of the following methods: Generating a random number Generating a random float and integer Generating random number arrays Generating random number from an array What is a random number? This is a number which cannot be predicted before its occurrence. This number might not different every time. Programmatically, they are two categories of random numbers: Pseudo-Random numbers True Random numbers. Just as programs which are written by programmers are a set of instructions, we must follow an algorithm to generate random numbers. Random numbers which are generated using an algorithm are called Pseudo-Random numbers. To generate a true random number, it is important to get the data from sources such as the keyboards, mou...

Introduction to Django

Hello. Welcome to another session on this platform. If you are new here, please do checkout our previous articles on python programming language and stay excited on this session. we are entering into one of python’s application called Django. In this article, we are going to discuss the following: What is Django Why must we use Django A brief history of Django Installation of Django Popularity of Django What is Django? Python has so many framework application and Django happen to be one of them. Being a python-based-framework, it is used to quickly create web applications. When building websites, django provides similar ready-made components to handle user authentication, forms, a way to upload components. Why use django? Django is very fast. It takes applications from concept to applications very quickly Django has thousand available packages in it when it is installed. With django, we can launch web applications is a matter of hours. Django is a highly is secured and helps...
