Frequently Asked Questions

What functions does this scientific calculator support?

It supports basic arithmetic (+−×÷), trigonometry (sin/cos/tan and inverses), logarithms (log/ln), exponents (x², xⁿ, eˣ), square roots, factorials and constants (π, e).

How do I use trigonometry functions?

First select whether you want degrees or radians using the DEG/RAD toggle, then click sin, cos or tan and enter the angle value.

Can I use this on mobile?

Yes — the calculator is fully responsive and works on smartphones, tablets and desktop computers.

Is a scientific calculator the same as a graphing calculator?

No — a scientific calculator performs calculations. A graphing calculator also plots functions as visual graphs. This tool is a scientific calculator.
