# Scientific Calculator

URL: https://hifreetools.com/science/scientific-calculator

> A full scientific calculator in your browser — trigonometry, logarithms, exponents, roots, factorials, constants, and memory, with degree, radian, and gradian modes.

## Quick answer

Enter an expression like sin(30) + 2^3 and press = to evaluate. It supports trigonometry (sin, cos, tan plus inverse and hyperbolic forms), logarithms (ln, log, log₂), exponents and roots (^, √, ∛), factorials (!), the constants π and e, memory keys, and DEG/RAD/GRAD angle modes — all in your browser.

Type or tap a full math expression. The calculator parses it with correct operator precedence and supports functions, powers (^), factorials (!), parentheses, the constants π and e, and the previous answer (Ans). Trigonometric functions interpret their argument in the selected angle mode (degrees, radians, or gradians). Memory keys (MR/M+/M−/MC) hold a running value. All computation is local to your browser.

## Examples

- Trigonometry in degrees: sin(30) → 0.5
- Powers: 2^10 → 1024
- Combined expression: log(1000) + 5! → 123

## FAQ

**Does it support degrees and radians?**
Yes. Switch between DEG, RAD, and GRAD; the trigonometric functions use the selected mode.

**Which functions are included?**
sin, cos, tan and their inverse and hyperbolic forms, ln, log (base 10), log₂, exp, √, ∛, abs, factorial (!), powers (^), plus the constants π and e.

**How does the memory work?**
M+ and M− update a stored value, MR inserts it into the expression, and MC clears it. Ans inserts the previous result.

**Is log base 10 or base e?**
log is base 10 and ln is the natural logarithm (base e). log₂ is base 2.

**Can I type expressions with the keyboard?**
Yes — type something like cos(60)+sqrt(9) and press Enter to evaluate.

**Is anything uploaded?**
No. The scientific calculator runs entirely in your browser.
