Using your calculator, find a solution forin RADIANS (if possible). If no solution exists, enter NONE.
Though many solutions may exist, you should only provide ONE answer (which comes from using the inverse trigonometric function keys on your calculator).
when
(round your answer to four decimal places)
I got what I believe to be the answer but I am being told its wrong
so i take $\displaystyle \tan (\theta-4)=0.25 \rightarrow \tan^-1( \tan (\theta-4)=\tan^-1(0.25)\rightarrow \theta-4=\tan^-1(0.25) \rightarrow \theta=18.03624347 $
Are my calculation correct?
