Degrees vs Radians
This calculator uses radians for trigonometric functions, which is the standard in mathematics and programming. To convert degrees to radians, multiply by π/180. For example, to find sin(30°), enter sin(30 * π / 180).
Factorial Limits
Factorial is supported for integers from 0 to 170. Beyond 170, the result exceeds JavaScript's maximum floating-point value (approximately 1.8 × 10³⁰⁸). Enter a number first, then press the n! button.
