How it works

  1. 1
    Type an expression

    Example: sin(30) + sqrt(2) * pi. Use ^ for exponent, ! for factorial, * for multiplication.

  2. 2
    Toggle DEG or RAD

    DEG treats trig arguments as degrees, RAD as radians. Inverse functions return the same unit.

  3. 3
    Read the result

    Result updates as you type. Use the keypad or your keyboard.
