Now solve the trig equations

\tan \frac{\theta}{2} = 1.366

and

[br]\tan \frac{\theta}{2} = -0.366

\tan \frac{\theta}{2} = 1.366

and

[br]\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)

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.

If you want to go over this topic, this is a really good explanation.
