Frequently asked questions

Does this scientific calculator support degrees and radians?

Yes. Flip the Deg/Rad toggle and all trigonometry functions (including inverses) adapt automatically.

Can I use exponent and scientific notation?

Yes — the ^ key computes powers and expressions like 2e5 are parsed as scientific notation.

Is the calculation history saved?

The history tape is kept for the current session; Pro subscribers can persist and export it.
