[GRASSLIST:1652] Using atan function

hello
(sorry if it is double message)

I want to make sure that using atan function.
I have two maps containing sin and cosine values in radian.
Using atan function in r.mapcalc is correct in this way:
r.mapcalc dene='atan(map_cosine*180/3.14,map_sine*180/3.14)' ?

kind regards
