Scientific Calculator — FAQ
1. Which functions are supported?
sin, cos, tan, asin, acos, atan, log (base 10), ln, exp, sqrt, abs, pow, and basic arithmetic (+ − × ÷).
2. Does the calculator use degrees or radians?
Trigonometric functions expect degrees by default and automatically convert them to radians internally.
3. Is it safe to enter long or complex expressions?
Yes — this tool uses a sandboxed safe parser, not eval or new Function.
Your input is processed securely.
4. Can I use parentheses?
Yes, expressions like (sin(30) + 5) * log(10) work perfectly.
5. Does it work offline?
Yes! All calculations run directly on your device without internet or servers.
