math library functions in python3

For using math functions we have import the math module which contains all the mathematical functions like sin,cos.. etc.

FOR IMPORTING MATH MODULE;

USE THE CODE:     

 import math 

some imprtant math functions in python

1)math.ceil(x)

   Return the ceiling of x as a float, the smallest integer value greater than or equal to x.

    example:

   math.ceil(4.1)    returns 5

2)math.floor(x)

  Return the floor of x as a float, the largest integer value less than or equal to x.

  example:

   math.floor(4.9)  returns 4

3)math.factorial(x)

  Return x factorial. Raises ValueError if x is not integral or is negative

  example:

  math.factorial(3)  returns 6

4)math.log(x[, base])

With one argument, return the natural logarithm of x (to base e).

With two arguments, return the logarithm of x to the given base,calculated as log(x)/log(base).

5)math.pow(x, y)

Return x raised to the power y. Exceptional cases follow Annex ‘F’ of the C99 standard as far as possible. In particular, pow(1.0, x) and pow(x, 0.0)always return 1.0, even when x is a zero or a NaN. I

#Unlike the built-in ** operator, math.pow() converts both its arguments to type float. 

6)math.sqrt(x)

Return the square root of x.

7)math.sin(x)

Return the sine of x radians.

8)math.tan(x)

Return the tangent of x radians.

9)math.pi

The mathematical constant π = 3.141592…, to available precision.

10)math.e

The mathematical constant e = 2.718281…, to available precision.
