    Now solve the trig equations \tan \frac{\theta}{2} = 1.366 and 

\tan \frac{\theta}{2} = -0.366

    So i got theta/2= 0.93888 and theta/2= -0,35088
    How do i put this into GS

    The general solution of \tan \frac{\theta}{2} = \alpha is \theta = 2(\tan^{-1} \alpha + k\pi)

    How do i get k? Will it not always be 2?

    Do you know what a general solution is? I think you need to review your knowledge before blindly attempting questions.

    Like Theta=(-0.702+2npi) Will k not =2n all the time?

    Yeah, you can write it like that if you want. It's exactly the same.
