HI!

arctan doesn't work properly when program is set on degrees.

Hello.

Thanks. Actually this is known issue of 0.89 version. Angle option will be no more supported by SMath Studio in future versions because we have now Units feature. Just use 'deg or 'rad units in order to specify the arguments of trigonometric functions (please, turn Angles options to Radians before doing this).

See also: degrees / radians.

Best regards.

Thank You for the fast answer. It works.
So in the future I should always turn Angles options to Radians, and if I want to use degrees (as in most of the time) I should give it this way a:=60'deg. Am I right?

By the way, your program is very useful! I like it very much!

Best regards

Most of all yes. Except you will not need to always set Angle option to Radians - Angle option is completely removed from the options dialog.
You can check the latest beta to try it out: http://en.smath.info/forum/default.aspx?g=posts&m=3387#post3387.

Note, you can also use '° Unit (press f.e. Ctrl+Space to see it) instead of 'deg.
