Frequently Asked Questions
Are trigonometric functions in degrees or radians?
This calculator uses radians for trigonometric functions. To convert degrees to radians, multiply by π/180. For example, 90° = 90 × π/180 = π/2 ≈ 1.571 radians.
What is the difference between ln and log?
ln is the natural logarithm (base e ≈ 2.718), while log is the common logarithm (base 10). ln(e) = 1 and log(10) = 1.
What does the x! (factorial) button do?
Factorial calculates the product of all positive integers up to that number. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120. It only works with non-negative integers.
