Description alfiodemartino 2013-05-05 18:52:46 UTC
why do you use radians instead of degrees? degrees are so much easily and immediately grasped and now we have to convert everything to radians. Is there a "switch" to make the program use degrees natively instead of radians?

In many areas of mathematics, Radians are more appropriate. 

However, what area of Calc are you referring to?
Comment 2 alfiodemartino 2013-05-06 06:34:50 UTC
I am not sure of what you mean but if you have trigonometry calculations 
that involve angles you usually have them in degrees since a protractor 
or anything like it gives readings in degrees and not in radians. Also 
any architectural drawing is in degrees and when someone refers to a 90 
(or 30 or 60 or 45) degree angle I know what he means but if he gives it 
in radians I have no clue unless we have a calculator handy, well 
actually not a calculator since it works in degrees too unless it has a 
function to convert degrees in radians. In all my mathematics classes we 
never ever used radians but only degrees.
For this I fail to understand the use of radians instead of degrees.

You still haven't told us what specific areas of Calc you are talking about. Which spreadsheet functions are you referring to specifically? 

Without this information there's not much we can do.

RADIANS(number)
is your friend

(and DEGREES(number) to go the other way around)
Comment 5 alfiodemartino 2013-05-06 11:49:54 UTC
Yes I am aware of the formulas but most people think in degrees and not 
in radians so this behavior is futile, useless and counterproductive 
also since most calculators work in degrees and if you refer to an angle 
of a triangle you refer to it as 30 degrees or do you think we should 
refer to it in radians? Protractors or any angle measuring device give 
readings in degrees which we have to re-translate to radians to put them 
in a spreadsheet?
Please get real.
In any case I am using SIN, COS and TAN formulas.

Actually, the division of an angle into 360 degrees is fairly arbitrary, whereas radians are a measure of length. You often need to use radians to make things like calculus easier.

No matter. A true show stopper is compatibility with Excel, which returns SIN, COS and TAN in radians.
