Depends on the author. There were plenty of subtly wrong tables back in the day.
These were often evaluated as Newton approximation, Taylor expansion or direct series if it converged fast enough.

Additionally the first accurate multiplication algorithm faster than long multiplication has only been devised in XX century - Karatsuba's. Abacus is just a mechanical tool that represents long addition and multiplication.
