Math Module Functions Guide

Here are a few useful math functions that are included in the math module. You must use include math and math. to access these functions. For a full list of math functions refer to the Python reference here: Math Module

1. math.sqrt():
   • Description: Returns the square root of a specified number.
   • Example:

     import math
     result = math.sqrt(16)
     print(result)  # Outputs: 4.0
     

2. math.pow():
   • Description: Similar to the built-in pow(), but specifically for floating-point numbers.
   • Example:

     import math
     result = math.pow(2, 3)
     print(result)  # Outputs: 8.0
     

3. math.exp():
   • Description: Returns ( e ) raised to the power of the provided number, where ( e ) is the base of natural logarithms.
   • Example:

     import math
     result = math.exp(1)
     print(result)  # Outputs: 2.718281828459045
     

4. math.log():
   • Description: Calculates the natural logarithm of a specified number. Optionally, a base can be specified.
   • Example:

     import math
     result = math.log(10)
     print(result)  # Outputs: 2.302585092994046
     

5. math.factorial():
   • Description: Returns the factorial of a number.
   • Example:

     import math
     result = math.factorial(5)
     print(result)  # Outputs: 120
     

6. math.sin():
   • Description: Returns the sine of a number given in radians.
   • Example:

     import math
     result = math.sin(math.pi / 2)
     print(result)  # Outputs: 1.0
     

7. math.cos():
   • Description: Returns the cosine of a number given in radians.
   • Example:

     import math
     result = math.cos(0)
     print(result)  # Outputs: 1.0
     

8. math.tan():
   • Description: Returns the tangent of a number given in radians.
   • Example:

     import math
     result = math.tan(math.pi / 4)
     print(result)  # Outputs: 1.0
     

9. math.radians():
   • Description: Converts an angle from degrees to radians.
   • Example:

     import math
     result = math.radians(180)
     print(result)  # Outputs: 3.141592653589793
     

10. math.degrees():
    • Description: Converts an angle from radians to degrees.
    • Example:

      import math
      result = math.degrees(math.pi)
      print(result)  # Outputs: 180.0
