Question 2993
 For this kind of question there is no correct answwer, since we only can
 have approximated answers.(dependng how accuracy is required.)

 As I showed you to use sin x  = x - x^3/6 
 or  x - x^3/6 + x^5/150 
 to get some values.

 If you use Newton's iteation method ,let f(x) = x -sin x - 3.4545
 xn+1 = xn - f(xn)/f'(xn) by choosing some xo(say 1) to start.

 Whatever methods you use , there is no correct answer.
