Re: cos

[Brian Kaczynski]

Hello,

I'm certain that this is because Octave assumes the argument to cosine is in radians, whereas your calculator assumes it is in degrees.

cos(1) returns 0.54030

My calculator Casio fx-100D returns cos(1) as 0.999847695.

Using Octave 4.0.0/Win8.1.

I am not sure whether to post this as a bug to http://savannah.gnu.org/bugs/?group=octave, as I still have not identified the mathematical roots of cosine.

Casio Headquarters are in Shibuqa, Tokyo Japan.
