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

    Frank,

    There's no magic to this, and there's no need to learn all sorts of arcane features of your calculator turning you into some sort of calculating robot.

    Could not agree more! That's why I asked about the innards of this calculation.

    Only those things can be remembered and used properly that I have understanding about.

    Regards,

    Tony.
