Hello,
It seems to be unnecessarily hard to numerically convert radians to degrees in Sage. For example, how does one convert arctan(4/5) radians to degrees?
The following
n(arctan(4/5))*sage.symbolic.units.convert(units.angles.radian,units.angles.degree)
returns
121.453369600239*degree/pi
Is there a simple way to just return a numerical answer (without multiplying by 180/pi)?
There's currently no way in Sage to do something like:
sage: angle_measurements('degrees')
sage: sin(90)
1
sage: arcsin(1)
90
At the moment, your best best is to either manually multiply/divide by 180/pi or write wrapper functions for the trig functions which do the conversions for you.

What is wrong with multiplying by 180/pi ?
I just wanted to see if it could be done with Sage's units module.
