Are trigonometric functions in degrees or radians?

Degrees. sin(90) returns 1, for example. Use radians manually by converting first (radians = degrees × pi / 180) if you need radian input.

What does log vs ln mean?

log() is base-10 logarithm; ln() is the natural logarithm (base e).

Is this safe from malicious input?

Yes — expressions are parsed by a dedicated evaluator that only understands numbers, operators, and a fixed list of math functions. No arbitrary code can be executed.

Formula

Expressions are parsed and evaluated with standard mathematical order of operations (parentheses, then exponents, then multiplication/division, then addition/subtraction).

e.g. sin(45) + sqrt(16) * 2 → 0.707 + 4 × 2 = 8.707

Step-by-step

1
Type an expression
Use +, −, *, /, ^ (power), % (modulo), and parentheses.
2
Use functions if needed
sin, cos, tan, asin, acos, atan (all in degrees), sqrt, log, ln, abs, exp, round, floor, ceil, min, max.
3
Read the result
Your expression evaluates live as you type.

Examples

Basic arithmetic

expression: (4 + 6) * 3 / 2

= 15

Trigonometry

expression: sin(30) + cos(60)

= 1

Roots and exponents

expression: sqrt(144) + 2^5

= 44
