How To Draw Square In Python

Introduction to Square Root in Python

Conversely, the square root of a number is a value that gives the original number when multiplied by itself. Every positive number has got two foursquare roots. (same value with positive and negative signs.) The following is the notation of Square Root: –

√25 = ±v

For a negative number, the square root of the number includes the circuitous numbers, the give-and-take of which is out of scope for this article.

Mathematical Intuition of Square

Nosotros all take learned in our babyhood that when a number is multiplied by itself, nosotros go the square of that number. Square of a number can be alternately thought of as multiplying a number that many numbers of times. Allow usa try to understand it with the assistance of an case: –

Permit united states of america suppose we want to get the square of five. If we multiply the number (in this case, 5) by v times, nosotros go the square of that number. The post-obit annotation denotes the square of the number: –

v² = 25

Square Root in Python

In Python, nosotros likewise need to use the square root functionality very frequently in our programming. At that place are multiple ways in which we can find the foursquare root of a number in Python.

i. Using Arithmetics Operator (power)

Code:

num = 25
sqrt = num ** (0.five)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Explanation: We tin brand use of the "**" operator in Python to go the foursquare root of a number. Any number raised to the power of one-half, i.due east. 0.five, gives the states the number's foursquare root.

2. Using math.sqrt()

The foursquare root of a number can be obtained using the sqrt function from python's math module, as shown above. Henceforth, nosotros would see 3 scenarios in which we would give positive, zero and negative numbers in an argument of the function and run across the result.

a. Giving a positive number every bit an argument.

Code:

import math
num = 25
sqrt = math.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

b. Giving zero as an argument.

Code:

import math
num = 0
sqrt = math.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

c. Giving a negative number as an argument.

Code:

import math
num = -25
sqrt = math.sqrt(num)
print("The foursquare root of the number "+str(num)+" is "+str(sqrt))

Output:

Explanation: When we give a negative number as an argument, nosotros get the following math domain error. And then the argument must be greater than 0. Then to tackle this outcome, we must apply the sqrt function from the cmath module.

3. Using cmath.sqrt()

post-obit are the examples using cmath.sqrt():

a. Giving a negative number as an argument.

Code:

import cmath
num = -25
sqrt = cmath.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Explanation: For negative numbers, we must use the sqrt function of the cmath module, which deals with mathematical computation on complex numbers.

b. Giving a complex number equally an argument.

Code:

import cmath
num = 4 + 9j
sqrt = cmath.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Explanation: For finding the square root of complex numbers also we can employ the cmath.sqrt() role.

4. Using np.sqrt()

Code:

import numpy equally np
num = -25
sqrt = np.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Caption: The square root of a positive, zilch, and circuitous number tin can be calculated with the assist of the in a higher place function.

5. Using scipy.sqrt()

Lawmaking:

import scipy every bit sc
num = 25
sqrt = sc.sqrt(num)
impress("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Caption: Like numpy sqrt function in scipy, also the foursquare root of positive, nada and circuitous numbers tin exist calculated successfully, just for negative numbers, nan is returned with RunTimeWarning.

6. Using sympy.sqrt()

Lawmaking:

import sympy equally smp
num = 25
sqrt = smp.sqrt(num)
print("The square root of the number "+str(num)+" is "+str(sqrt))

Output:

Explanation: The sympy is a module for the python module for symbolic mathematics. With the help of sympy.sqrt() function we can go the square root of positive, zippo, negative and complex numbers. The just departure between this method and other methods are in this method when the statement is an integer, then the square root is likewise an integer, unlike the other cases where the square root is always floating no matter the datatype of the argument.

Determination

Finally, we come up to the closure of this commodity in which we had a brief introduction to square root function in mathematics. And so we discussed the internal functionality of a square root function and its implementation. We finally ended by looking at the different methods of applying the square root part in Python.
