EXERCISE 137 : Solve complex computing problems by
using builtin modules

Objectives

At the end of this exercise you shall be able to
• develop python programs to Solve complex computing problems by using builtin modules.

Procedure

TASK 1: Finding the Square Root with the math Module
Code:
import math

number = float(input(“Enter a number: “))
square_root = math.sqrt(number)
print(f”The square root of {number} is {square_root}”)
Explanation:

1 Importing the math Module:
• import math: This line imports the math module, which provides access to various mathematical functions and
constants.
2 Getting User Input:

• number = float(input(“Enter a number: “)): This line prompts the user to enter a number. The input is captured
as a string using the input() function and then converted to a floating-point number using float().
3 Calculating the Square Root:

• square_root = math.sqrt(number): This line calculates the square root of the input number using the sqrt()
function from the math module.
4. Displaying the Result:

• print(f”The square root of {number} is {square_root}”): This line prints the calculated square root using an
f-string. It displays the original number entered by the user along with its square root.
Output:

TASK 2: Calculating Trigonometric Functions with the math Module

Code:
import math
angle = float(input(“Enter an angle in degrees: “))
sin_value = math.sin(math.radians(angle))

cos_value = math.cos(math.radians(angle))
