Scientific Calculator
Evaluate complex scientific math expressions with trigonometric functions, logarithms, exponents, constants (π, e), and degree/radian angle modes.
How It's Calculated
Formula
\text{Result} = f(x, y, \dots)A deterministic, client-side scientific calculator for evaluating advanced arithmetic, trigonometric operations, powers, roots, and logarithms. Expressions are parsed using standard mathematical order of operations (PEMDAS): Parentheses, Exponents (right-associative), Multiplication and Division, and Addition and Subtraction.
Worked Examples
Trigonometric and Algebraic Evaluation: sin(30) + 2 ^ 3
- Evaluate exponent: 2 ^ 3 = 8.
- In Degrees mode, evaluate sine: sin(30°) = 0.5.
- Compute addition: 0.5 + 8 = 8.5.
Frequently Asked Questions
How do I toggle between Degrees and Radians?
Use the 'Angle Unit Mode' dropdown above the expression input. When Degrees is selected, sin(90) equals 1. In Radians mode, sin(pi / 2) equals 1.
What functions are supported?
The calculator supports sin, cos, tan, asin, acos, atan, log (base 10), ln (natural log), sqrt (square root), abs (absolute value), powers (^), and constants pi and e.
Is my expression evaluated safely?
Yes. Evaluation uses an in-repo recursive descent parser with zero JavaScript eval() or dynamic code execution, ensuring complete security against arbitrary code injection.
