I am going through this,quite straightforward ...just some bit of clarity from your end; the textbook indicates, the argument as ##-2.90## i have no problem with that as tan cycles at every ##\pi## radians. The problem is that i am not used to this approach.
My approach is more straightforward i.e
##\tan \alpha= 0.25##
##\alpha= \tan^{-1} 0.24 = 0.2449##
##\alpha_{required angle}= \pi + 0.2449=3.386=3.39 ##(2 dp) My question is' does it matter or there is a systematic approach to this; are both approaches valid. Of course, i can see that going backwards ( in terms of cycle) ##[3.386-\pi]=[0.244-\pi]=-2.8971##
Thanks.
or to answer my own question, it depends on the domain given.
