Math Module

What is math Module ?

For mathematical operations like trigonometric operation, logarithmic operation, angle conversion, etc. python has a built-in standard module which is known as math module. You can use this module by using import math.

• Some standard math modules are:
  • Angle Conversion Operation
  • Trigonometric Operation 
  • Logarithmic Operation
  • Basic Mathematical Operations
  • Mathematics Constants

Angle Conversion Operation :

• Conversion of degree to radian or vice versa.
•  
  • math.degrees() – This method is used for conversion of angle in radians to angle in degrees : – 3.1416 rad = 180°

Output is as below :

• math.radians() – This method is used for conversion of angle in degrees to angle in radians : 180° = 3.14159 rad

Output is as below :

Trigonometric operation : 

• This operation is used to find out sine, cosine or tangent value of a number.
• This module by default took angle parameter value in radians.
• So if you have angle in degree unit, first convert it in radian unit by using math.radians() method.

• math.cos() – It gives cosine value of  number or of an angle in radians.

Output is : 

• math.sin() –  It gives sine value of  number or of an angle in radians.

Output is:

• math.tan() – It gives tangent value of  number or of an angle in radians.

Output is :

• math.cosh() – It gives hyperbolic cosine value of  number or of an angle in radians.

Output is :

• math.sinh() –  It gives hyperbolic sine value of  number or of an angle in radians.

Output is: 

• math.tanh() – It gives hyperbolic tangent value of  number or of an angle in radians.

Output is :

Logarithmic Operation:

• This operation is used to find out logarithmic values of parameters
•  
  • math.log() – It gives the natural logarithm of a number. – loge(x) or ln(x)

Output is :

• math.log(x,y) – It gives the logarithmic value of ‘x’ parameter with base ‘y’. – logy(x)

Output is :

• math.log10() – It gives logarithmic value of a number with base-10. – log10()

Output is :

• math.log2() – It gives logarithmic value of  a number with base-2. – log2()

Output is :

Basic Mathematical Operation :

• Mathematical operations like square root, factorial, absolute, reminder, round-up, power, etc.

• math.ceil() – It round up the number upward to  nearest integer.

Output is :

• math.floor() – It round up the number downward to nearest integer.

Output is :

• math.fabs() – It gives absolute value of the number.

Output is :

•  math.factorial() – It gives factorial value of the number.

Output is :

• math.fmod(x,y) – It gives reminder of  x/y value.

Output is :

•  math.pow(x,y) – It gives ‘x’ raised to the power of ‘y’.

Output is :

• math.gcd(x,y) – It gives greatest common divisor of x & y.

Output is :

Mathematics Constants :

• The well-known mathematics constant is pi (π)
• The ratio of  circumference of a circle to the  diameter of  that circle is ‘pi’ constant.
• Mathematically it is calculated as  22/7 = 3.14159

• math.pi It gives value of ‘pi’ constant.

Output is :
