Scientific Calculator
Evaluate scientific expressions with arithmetic, powers, roots, trig functions, logs, parentheses, and constants. Choose degrees or radians for trig.
Supported: + - * / ^ ( ) sqrt() sin() cos() tan() log() ln() abs() pi e. Use Enter to calculate.
Privacy: calculations run locally in your browser. No expressions are stored or transmitted.
How it works
Expressions are validated, converted into safe JavaScript math calls, and evaluated locally.
Trig functions use the selected angle mode. Example:
sin(30) in degree mode = 0.5
Examples
- 2^3 + sqrt(16) = 12
- sin(30) in degrees = 0.5
- ln(e) = 1
