Frequently Asked Questions

How do I switch between degrees and radians?

Click the "Deg"/"Rad" button at the top of the calculator — it toggles how sin, cos, tan and their inverse functions interpret angle values.

Can I use my keyboard to type calculations?

Yes — number keys, operators, Enter (equals), Backspace and Escape (clear) all work directly.

What does x^y mean?

It raises the first number to the power of the second — for example, 2 x^y 3 calculates 2³ = 8.
