So is the general solution: theta= +/- 222+360k

Then is it legal to ....

-222+360(1)????

222+360(0)=222(just like your answer)

How come there is only one answer????

**Steve**, Friday, November 15, 2013 at 6:26amthere is usually only one answer because the domain is restricted to

0 <= theta < 360

I mean, who cares about the other equivalent angles? They're all the "same" angle.
