WebPretty much, yes.... if you want to be "nit-picky" about it, 3.14 radians = 179.90875 degrees. In general, it's better to use pi instead of a rounded approximation like 3.14 or 22/7 or something like that. By the way, 22/7 radians = 180.07245 degrees. 2 comments. WebOct 29, 2013 · Because, as you pointed out, the angle is in the 2nd quadrant. This means that θ is between and (roughly, between 1.5 and 3). The sin -1 function returns an angle between and , as does tan -1. The cos -1 function returns an angle between 0 , which was the correct interval for your angle. Post reply.
