Arithmetic Operations

Python supports all basic arithmetic operations, such as addition, subtraction, multiplication, division, and modulus.

Here are some examples of arithmetic operations in Python:

python # Addition result = 1 + 2 print(result) # Output: 3

# Subtraction result = 10 - 5 print(result) # Output: 5

# Multiplication result = 3 * 4 print(result) # Output: 12

# Division result = 12 / 3 print(result) # Output: 4.0

# Modulus result = 10 % 3 print(result) # Output: 1

Power and Exponentiation

To calculate the power or exponent of a number, you can use the pow() function from the math module.

python # Power using pow() function result = math.pow(2, 3) print(result) # Output: 8

# Exponentiation using ** operator result = 2 ** 3 print(result) # Output: 8

Absolute Value and Rounding

You can use the abs() function to find the absolute value of a number and the round() function to round a number to a specified number of decimal places.

python # Absolute value using abs() function result = abs(-5) print(result) # Output: 5

# Rounding using round() function result = round(3.14159, 2) print(result) # Output: 3.14

Algebraic Operations

Python supports various algebraic operations, including solving equations, finding roots, and performing matrix operations.

Solving Equations

To solve a linear equation of the form ax + b = 0, you can use the sympy library.

python import sympy x = sympy.Symbol('x') equation = sympy.Eq(x + 2, 0) result = sympy.solve([equation], (x,)) print(result) # Output: [-2]

Finding Roots

To find the roots of a polynomial, you can use the numpy library.

python import numpy as np coefficients = [1, -2, 1] roots = np.roots(coefficients) print(roots) # Output: [1.+0.j 1.-0.j]

Matrix Operations

To perform matrix operations, you can use the numpy library.

python import numpy as np A = np.array([[1, 2], [3, 4]]) B = np.array([[5, 6], [7, 8]])

# Matrix addition C = A + B print(C) # Output: [[ 6 8] [10 12]]

# Matrix multiplication D = np.dot(A, B) print(D) # Output: [[19 22] [43 50]]

Calculus Operations

Python provides limited support for calculus operations through the sympy library.

Differentiation

To differentiate a function, you can use the diff() function from the sympy library.

python import sympy x = sympy.Symbol('x') function = x**3 + 2*x**2 - 5 derivative = sympy.diff(function, x) print(derivative) # Output: 3*x**2 + 4*x

Integration

To integrate a function, you can use the integrate() function from the sympy library.

python import sympy x = sympy.Symbol('x') function = x**2 + 2*x - 3 integral = sympy.integrate(function, x) print(integral) # Output: x**3/3 + x**2 - 3*x + C

Practical Applications

Math operations in Python find extensive use in various practical applications, such as:

• Data analysis and visualization
• Scientific computing and modeling
• Machine learning and artificial intelligence
• Finance and economics
• Game development

This guide has provided a comprehensive overview of ng math with Python, covering a wide range of topics from basic arithmetic to advanced calculus operations. By mastering these concepts, you can harness the power of Python for various scientific and engineering applications. Remember to practice and experiment with different mathematical operations to deepen your understanding and become proficient in Python's mathematical capabilities.
