Expression help
You can combine functions and operators in a single expression. Examples:
  • 2 * sin(0.5) + sqrt(9)
  • (3^2 + 4^2) ^ 0.5 (hypotenuse)
  • ln(5) + 2 * PI
The calculator treats ^ as exponentiation using JavaScript’s ** operator.

Supported functions and constants

This calculator uses the standard JavaScript Math library under the hood. It supports:

  • Trig: sin(x), cos(x), tan(x) (radians)
  • Roots & powers: sqrt(x), x^y, x²
  • Logarithms: ln(x) (natural log)
  • Constants: PI (π), E
  • Basic ops: +, −, *, /

Keyboard tips

You can also type directly into the calculator:

  • Use sin(, cos(, tan(, sqrt(, log( (for ln)
  • Press Enter to evaluate, Backspace to delete
  • Use PI and E if you type by hand

This tool is for convenience only. Always double-check important or critical calculations.
