math library in python

Comment

Python comes with a built-in math library called `math` which provides various mathematical functions and constants. Here is an example of how you can use the `math` library in Python:

import math

# Calculate the square root of a number
num = 16
sqrt = math.sqrt(num)
print("Square root of", num, "is", sqrt)

# Calculate the factorial of a number
num = 5
factorial = math.factorial(num)
print("Factorial of", num, "is", factorial)

# Calculate the sin of an angle in radians
angle = math.pi / 4
sin = math.sin(angle)
print("Sin of", angle, "is", sin)

# Calculate the logarithm base 10
num = 100
log = math.log10(num)
print("Logarithm base 10 of", num, "is", log)

python math methods

Comment

Python has a built-in math module that provides a set of functions for mathematical operations. Here are some commonly used math methods in Python:

abs(): Returns the absolute value of a number.

ceil(): Returns the smallest integer greater than or equal to a number.

floor(): Returns the largest integer less than or equal to a number.

round(): Returns the nearest integer to a number.

sqrt(): Returns the square root of a number.

pow(): Returns the value of a number raised to a specified power.

log(): Returns the natural logarithm of a number.

log10(): Returns the base-10 logarithm of a number.

exp(): Returns the value of e raised to the power of a specified number.

cos(): Returns the cosine of a number in radians.

sin(): Returns the sine of a number in radians.

tan(): Returns the tangent of a number in radians.

acos(): Returns the inverse cosine of a number in radians.

asin(): Returns the inverse sine of a number in radians.

atan(): Returns the inverse tangent of a number in radians.

Here's an example of using some of these methods:

import math

# Absolute value
x = -5
print(abs(x))

# Ceil and floor
y = 3.7
print(math.ceil(y))
print(math.floor(y))

# Round
z = 2.6
print(round(z))

# Square root and power
a = 16
print(math.sqrt(a))
print(pow(a, 2))

# Logarithm
b = 10
print(math.log(b))
print(math.log10(b))

# Exponential
c = 2
print(math.exp(c))

# Trigonometric functions
angle = math.pi / 4
print(math.cos(angle))
print(math.sin(angle))
print(math.tan(angle))
print(math.acos(math.sqrt(2)/2))
print(math.asin(math.sqrt(2)/2))
print(math.atan(1))

This will output:

4.0

256

2.302585092994046

1.0

7.3890560989306495

0.7853981633974484
