1. What is a Scientific Calculator?

A scientific calculator is a type of electronic calculator designed to calculate problems in science, engineering, and mathematics. It can handle trigonometric functions, logarithms, powers, roots, and other complex mathematical operations.

2. How Does This Calculator Work?

This online scientific calculator uses JavaScript's built-in Math functions to perform calculations. It supports:

• Basic arithmetic operations (+, -, ×, ÷)
• Trigonometric functions (sin, cos, tan, asin, acos, atan)
• Logarithmic functions (log, ln, log10)
• Exponential functions and powers (x^y, exp, sqrt)
• Constants (π, e)
• Advanced functions (abs, floor, ceil, random)

3. Key Features

Details: This calculator provides all the functionality of a physical scientific calculator in a convenient online format. It's accessible from any device with a web browser and doesn't require installation.

4. Using the Calculator
