Frequently Asked Questions

Are trig functions in degrees or radians?

This calculator uses degrees. To convert: radians = degrees × (π/180).

What does the M+ button do?

M+ adds the current display to memory. MR recalls the stored value. MC clears memory.

How do I calculate powers?

Use xʸ button: enter base, press xʸ, enter exponent, press =. Or use x² for squaring.

What is log vs ln?

log is base-10 logarithm. ln is natural logarithm (base e ≈ 2.718).
