Check Pythagorean triplet using Matlab

Program

We know that the Pythagorean is an equation which satisfies the following condition:
a2 + b2 = c2
Write a program with Matlab, which takes the user input of the numbers and checks if the above condition is satisfied. If the condition is satisfied then display the success to the user.

Right angle triangle

Solution

We take the user input and then use the if else statement to check if the user has entered three number which are in accordance to the Pythagorean theorem and display the success using the fprintf in Matlab.
Some of the concepts you need to know to solve the above problem are as follows:
1) User input using input function
2) if else statement in Matlab
3) fprintf in Matlab

a = input('Enter length of Opposite side(a): ');
b = input('Enter the length of Adjacent side(b): ');
c = input('Enter the length of Hypotenuse(c): ');

if a^2 + b^2 == c^2
    fprintf('Thats a pytagorean triplet\n');
else
    fprintf('Sorry not a pythagorean triplet\n');
end
I have saved this file as pythagorean.m on my local computer.

Explanation

I have asked the user to input their values for the length of the sides of the triangle and using the if else I have checked the Pythagorean condition and if the condition is satisfied then display the user that the triplet entered is Pythagorean triplet. Otherwise(else), display not a Pythagorean triplet.

Try it yourself

1) In the above program even if the user enters negative values it checks the values for the pythagorean triplet. But this is not in the real case. Write a program such that if the user enters negative values then display that they have entered invalid numbers. Comment your program in the comment box below.

Problem 60 Project Euler Solution with python

Prime pair sets The primes 3, 7, 109, and 673, are quite remarkable. By taking any two primes and concatenating them in any order the result will always be prime. For example, taking 7 and 109, both 7109 and 1097 are prime. The sum of these four primes, 792, represents the lowest sum for a set of four primes with this property. Find the lowest sum for a set of five primes for which any two primes concatenate to produce another prime. This problem is j u st a brute force problem. If you have come here because you don't know the limit upto which you will h ave to gener ate the prime numbers t hen go ahe ad and t r y with 10,000 . When I first start ed solving the problem I chose 1 million(beca use most of the problem s on project E uler have this limit ), but it took very long for the computer to fin d the solution. After searching on the internet then I found many people choosing 10, 000 so I have changed my in put f rom 1 million to 10000 and the output was f ast. He

Add/Embed SVG to Blogger website

In this post I will tell you my method(trick) of adding SVG images in a blogger website or blog. Before starting , the first thin g I am assu m ing is that you are aware of SVG if you are here. If not please see S calable V ec tor G raphics Recently when I tried to embed a SVG image for a post on pygal, I tried uploading the SVG file and blogger Image uploader came up with an error, because of which I had to find some other way.  SVG File upload Error in Blogger  I started sea rc hing Google " Embed SVG in Blogger " . I found blogorrhea , w h ich gave some i nformatio n on add ing SVG directly as a markup , which worked , but I faced another problem using this . Also th is guy has used lot of Javascript which was confusin g for me, being new to using SVG.   So I first t houg ht of learning on h ow to embed SVG in HTML and t his on e worked out. Actually we can embed SVG in HTML i n following ways: Using Object tag Using Iframe tag Using embed tag Us

Making a quiz web app with python and flask

Edit : When you are creating a web app with h tml templates, then y ou will have to sa ve the html file in templates folder in the Current Wor ki ng Directory( CWD). If you save the file in the C W D directl y you will get a TemplateNotFound error. Thank you Udhay for pointing it out.   In this post we will create a quiz website using python . I will be using the flask framework . After reading this tutorial you will learn form submission , flask templates , python code in flask templates , shuffling the questions and options with the random module and few others.  Please note that this tutorial is not big as it seems to be. Some of the code has been rewritten to maintain consistency and also font size is somewhat big so that your eyes won't get stressed reading this tutorial. Also the content has not occupied the full width of the page. In this tutorial I am assuming that you are having a very basic understanding of the flask framework . Please refer the documentation
