## Solving High-Order Polynomial Equations in Python Examples and Tutorial

A polynomial equation is an equation of the form ax^n + bx^(n-1) + cx^(n-2) + … + dx + e = 0, where a, b, c, d, and e are constants and x is the variable. The solutions to a polynomial equation are the values of x that make the equation true. One common method …

## Mastering Python Variables: Tips, Tricks, and Hands-on Examples

In Python, a variable is a way to store and access a value in the memory of a computer. A variable is assigned a value using the assignment operator (=), and the value of the variable can be accessed by referencing its name. For example: This code will output 5, because the variable x is …

## Simple math python code for students

Here’s an example of how to define a simple function in Python: Copy codedef greet(name): print(“Hello, ” + name + “!”) greet(“John”) # prints “Hello, John!”greet(“Jane”) # prints “Hello, Jane!” In this example, the function greet() takes one argument, name, and prints a greeting using that argument. We can call the function multiple times with different arguments to get different greetings. …

## Atomic Theory History

Atomic theory is a scientific theory that explains the nature of matter at the atomic and subatomic level. The theory was first proposed by John Dalton in the early 19th century and has since been developed and refined by many scientists, including J.J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrödinger. Background of Atomic Theory …

## What is a mole?

Mole is the fundamental concept in chemistry. This is required to understand molecules and atoms. We can use this concept for subatomic things also. Like, electrons, protons etc. Now the question is, what is a mole? Can you weigh the single atom or molecule? No, it is not possible. Still we have made an instrument …
