⚡ Quick Answer
A scientific calculator performs advanced mathematical operations beyond basic arithmetic — including trigonometry (sin, cos, tan), logarithms (log, ln), powers, square roots, factorials, and constants like pi (3.14159) and e (2.71828). Use it for maths, physics, chemistry, and engineering.

🤔 How Does This Work?
Our Scientific Calculator evaluates mathematical expressions using JavaScript's built-in Math library:
- Trig functions: sin, cos, tan (input in degrees, converted to radians)
- Logarithms: log (base 10) and ln (natural log, base e)
- Powers: x^y using the ** operator
- Square root: sqrt() using Math.sqrt()
- Constants: pi = 3.14159265... and e = 2.71828182...
- Factorial: n! calculates the product of all positive integers up to n
