Calculator

This project is a simple scientific calculator built with HTML, CSS, and JavaScript. The calculator provides both basic arithmetic operations and advanced scientific functions, including trigonometric calculations, exponents, and square roots.

Features

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• Scientific operations: exponentiation, trigonometric functions (sin, cos, tan), and square roots.
• Use of the mathematical constant π (Pi).
• Advanced mode for trigonometric and scientific functions that can be toggled on and off.
• History panel to keep track of previous calculations.
• Keyboard input support for better user experience.

Installation

1. Clone this repository to your local machine:

   git clone https://github.com/FreecssY/Calculator.git

2. Navigate into the project directory:

   cd Calculator

3. Open the public/index.html file in your preferred web browser to use the calculator.

Usage

• Click on the buttons to enter numbers and operations, or use your keyboard for input.
• Use the "Advanced" button to toggle additional functions like sin, cos, tan, square root, and exponentiation.
• The calculator history displays the last few calculations and can be adjusted in size.
• Use the backspace button (←) to delete the last character or operation.
• The "C" button clears the entire display.

Keyboard Shortcuts

• Numbers: 0-9
• Decimal point: .
• Basic operators: +, -, *, /
