FAQ
What angle units?+
Choose degrees (0โ360) or radians (0โ2ฯ). Korean high school exams use degrees; university math typically uses radians.
Which functions are supported?+
sin, cos, tan, asin, acos, atan, log (base 10), ln (natural log), sqrt (โ), pow, abs, exp, and other standard functions.
Can it draw graphs?+
For plotting, use [Graphing Calculator]. For LaTeX formulas, use [Formula Builder].
Very large or small numbers?+
Supports JavaScript floating point range (~ยฑ1.8ร10ยณโฐโธ). Beyond that auto-displays as e+ notation.
Multiple expressions at once?+
Variables aren't supported, but you can copy results and chain them in the next expression.
Scientific notation?+
Large results show as 1.23e+10. You can also input that way (e.g., 1.5e3 = 1500).
