    Re: Which calculator to use for "arctan(tan(269))"?

    Tack så mycket, Lars!

    In a post called "POL and arctan2" from 2005 Nov 14, id w26304 that I wrote you will find an answer.

    I was about to try using the arccos() after reading your post but without the Robin's further help I could not get any further.

    Hope somebody will compile all those nice tips and tricks about using pocket calculators for AN purposes.

    Thank you again.

    Regards,

    Tony
