Scientific Calculator

Summary

A full-featured scientific calculator with trig, logarithms, exponents, factorial, and parentheses — all computed in your browser.

How it works

1. Click number and operator buttons or type directly on your keyboard.
2. Use sin, cos, tan for trigonometric functions; toggle DEG/RAD to switch angle mode.
3. Use ln for natural logarithm and log for base-10 logarithm.
4. Use x² to square, xʸ to raise to any power, and √ for square root.
5. Use n! to compute the factorial of the current number.
6. Press = or Enter to evaluate; press AC to clear the display.
