 Mar 21 comment Inconsitent general solutions of trigonometric equations @corbah You are correct. Upon considering the negative values, they give the solutions for x that positive values didn't, e.g. $x = 210^\circ$. However, all the extra values, they'll just simply have to be rejected because they didn't fit the original equation of sin x = sin 30deg, correct?

I guess the question is wrong then.

I think then it must be dividing the line segment externally, now I get it. I was confused since this was the first time when I encountered a negative ratio.
