Scientific Calculator

How it works

1. 1Type any expression using numbers, operators (+, −, ×, ÷, ^), parentheses, functions (sin, cos, tan, sqrt, ln, log, exp, cbrt, abs, asin, acos, atan), and constants (pi, e).
2. 2The result updates instantly. Trig functions use radians — write pi for π (e.g. sin(pi / 6)).
3. 3If the expression is malformed or names something unknown, the result shows — instead of an error.

Use cases

• Evaluate multi-step arithmetic like (3^4 − 7) / sqrt(2) without switching apps.
• Check trig values and identities — confirm sin(pi/2) = 1 or cos(0) = 1.
• Explore logarithm and exponential relationships such as ln(exp(5)) or log(1000).

Frequently asked questions

What operators and functions are supported?

Operators +, −, *, /, and ^ (power); parentheses; trig functions sin, cos, tan, asin, acos, atan; plus sqrt, cbrt, abs, ln (natural log), log (base 10), and exp. Constants pi and e are built in.

Are angles in degrees or radians?

All trig functions use radians. To use degrees, multiply by pi/180 — for example sin(30 * pi / 180) gives sin(30°) ≈ 0.5.

Why does the result show —?

The calculator returns — for any expression that is syntactically invalid, references an unknown name, or produces a non-finite value (such as 1/0 or sqrt(−1)).
