I tried sorry if it’s wrong hehe (May have been careless perhaps you could tell me the correct answer then I’ll figure it out)

Thank you very much! May I ask why reject the negative theta angle value? Is theta and alpha the same? Alpha more than zero applies the same as theta more than zero?
OH HAHAH i just realised i saw wrongly. It probably should be accepted? Since they did not give a domain. Unless the ans sheet says otherwise if you have one.
The answer given doesn’t include the negative angle as well... I’m confused now...
Hmm is there any context to this question which would eliminate the possibility of a negative value?
