Scientific calculator
Evaluate expressions with familiar scientific functions. Use sin(30), sqrt(9), 2^3, or parentheses.
Functions: sin, cos, tan, asin, acos, atan, sqrt, log, ln, abs, factorial (!). Use * for multiplication. Trigonometry uses degrees by default.
Expressions are parsed locally; the calculator does not execute JavaScript. Factorials are limited to non-negative integers up to 170.
