Frequently Asked Questions
Degrees vs Radians — which should I use?
Use DEG mode for everyday angle calculations (e.g., right triangles, navigation). Use RAD mode for calculus, physics, and programming where angles are in radians. The mode only affects trig and inverse trig functions.
How does xʸ work?
Enter the base (x), press xʸ, enter the exponent (y), then press =. Example: 2 xʸ 10 = 1024.
What is n! (factorial)?
Factorial multiplies a positive integer by all positive integers below it. 5! = 5 × 4 × 3 × 2 × 1 = 120. This calculator supports factorials up to 170!.
