This is a fairly simple notation problem. I am trying to compute ArcTan of the point (5,2). I have the code:
ArcTan[5,2]
which outputs:
ArcTan[2/5]
Do I have to clarify that I would like my output in terms of radians or Pi? Technically the output is correct, but not very useful.
Ideally I would found that the Arctan[5,2]=Arctan(2/5)=.3805. Which I guess would be found by using N[function]. Any ideas on how to get where it is Pi*x such that x in Reals?
I have used the page: https://reference.wolfram.com/language/ref/ArcTan.html. For help
N

. Note the period following the 2. This will output it in radians. If you want degrees useArcTan[5,2.]/Degree
