Scientific Calculator
A free online scientific calculator supporting trig, logs, exponents, and constants like π and e.
How it works
Operator precedence: functions → ^ → *, / → +, −. Parentheses override precedence.
sin(pi/4) + sqrt(2)^2 ≈ 2.707.
Frequently asked questions
- Which functions are supported?
- sin, cos, tan, log (base-10), ln, sqrt, exp, abs, plus π and e.
- Are angles in radians?
- Yes — pass π/180 · degrees to convert.
- Can I chain expressions?
- Yes — any valid math expression with parentheses is accepted.
- Does it show steps?
- No — this is a direct evaluator.
