sqrt() Function Examples
Let’s look at some different uses of math.sqrt() function.
Example 1: Check if Prime or Not
In this example, we are given a number and we are checking if a number is prime or not. Here,run a loop from 2 to sqrt(n) and check if any number in range (2-sqrt(n)) divides n.
Python3
# Python program for practical application of sqrt() function # import math module import math # function to check if prime or not def check(n): if n = = 1 : return False # from 1 to sqrt(n) for x in range ( 2 , ( int )(math.sqrt(n)) + 1 ): if n % x = = 0 : return False return True # driver code n = 23 if check(n): print ( "prime" ) else : print ( "not prime" ) |
prime
Example 2: Finding Hypotenuse Of a Triangle
In this example, we are using sqrt() function to find the hypotenuse of a triangle.
Python3
a = 10 b = 23 import math # importing the math module c = math.sqrt(a * * 2 + b * * 2 ) print ( "The value for the hypotenuse would be " , c) |
The value for the hypotenuse would be 25.079872407968907
