Polynomial Graph using Python

Polynomial Graph

Introduction to Polynomial Graph

Polynomial curve a is smooth and continues line of graph, connected by a series of co-ordinates calculated using a polynomial equation (For example, y = f(x), where f(x) = Ax2 + Bx + C). In this program, I have used a polynomial equation y = 3x2 + 4x + 2 with x values range from 0 to 5. The program generated co-ordinate points (x, y) in the graph will be (0, 2), (1, 9), (2, 22), (3, 41), (4, 66), and (5, 97).

Program Implementation

In this tutorial, I have used Python 3.5.2 (64-bit) software, and 7 modules: MatPlotLib 2.0.2, PyParsing 2.2.0, Python-DateUtil 2.6.1, PyTZ 2017.2, SetupTools 36.2.0, Cycler 0.10.0, and NumPy-MKL 1.13.1 implemented in Windows 10 Enterprise operating system. The 7 modules are chosen based on the compatibility of Python and OS version and bit.

Source Code

import numpy as np
import matplotlib.pyplot as plt

a = 3
b = 4
c = 2
x = np.linspace(0, 10, 256, endpoint = True)
y = (a * (x * x)) + (b * x) + c

plt.plot(x, y, '-g', label=r'$y = 3x^2 + 4x + 2$')

axes = plt.gca()
axes.set_xlim([x.min(), x.max()])
axes.set_ylim([y.min(), y.max()])

plt.xlabel('x')
plt.ylabel('y')
plt.title('Polynomial Curve')
plt.legend(loc='upper left')

plt.show()

    The graph of a polynomial function will also touch the x-axis with multiples. The graph will cross the x-axis at zero with oddities. The sum of the multiplications is the degree of the polynomial function. Learning maths is really interesting. Getting into a problem and then finding its solution is a fun. Maths used to be one of my favourite subject in school. Thanks for this questions for practice. This e-learning site is very helpful for the students. As mathematics is tricky but at the same time this is interesting too. By solving this students can practice for the further mathematics based exams. There are also a best guides where you can learn mathematics. With the help of h1 math tuition you can get easy tricks and methods related to maths.

Simple Server and Client Chat using Python

By

In Python language, socket (or network socket) is a module used to communicate between two computers. It provides two types of interface to access the network, namely low-level (platform dependent connections — Example: Telnet) and high-level (application dependent connections — Example: HTTP, FTP, SMTP, etc.). This is a simple tutorial to establish the low-level socket connection between server and client to communicate messages using the TCP/IP protocol. Server and Client Chat In this tutorial, I have used two scripts server.py to serve data by sending an invitation to the client, and client.py to receive data on acceptance of the invitation. After accepting the invitation, both server and client share messages mutually. — Server — An server script performs the sequence of functions such as socket() , bind() , listen() , and accept() (repeats for more than one client) to communicate with the client. The description of each functions used in the server script are given be

RNA to Protein Translation in PERL

By

In PERL programming, an RNA sequence can be translated to a protein sequence by substituting equivalent amino acid characters to triplet characters of RNA. This method has followed to find six reading frames (three in the forward direction, and three in the reverse direction). In this program, I have used the associative array (also known as a hash array) to associate triplet characters with amino acid characters. The associate array corresponding to codon table is arranged to 20 amino acid character. The triplet codon table is shown below: Source Code: print "Enter the RNA sequence: "; $rna = <>; chomp($rna); $rna =~s/[^acgu]//ig; my $rna = uc($rna); my(%genetic_code) = ( 'UCA' => 'S', # Serine 'UCC' => 'S', # Serine 'UCG' => 'S', # Serine 'UCU' => 'S', # Serine 'UUC' => 'F', # Phenylalanine 'UUU' => 'F', # Phenylalanine 'UUA' =&g
