Frequently Asked Questions

What is a scientific calculator?

A scientific calculator performs advanced mathematical functions like trigonometry, logarithms, exponentials, and statistical calculations beyond basic arithmetic.

Are trig functions in degrees or radians?

You can switch between degrees and radians using the deg/rad buttons. Default is degrees for convenience.

How do I calculate powers?

Use x² for square, xʸ for any power. For example: 2 xʸ 3 = 8 (2³).

What's the difference between log and ln?

log is base 10 logarithm, ln is natural logarithm (base e). Both are essential for scientific calculations.

Is my data private?
