Actually +/- means either one is a solution for x, which it obviously isn't.

No, that is exactly what ± does not mean, as I have already stated. Your interpretation leads to fuzzy logic, while the standard interpretation is really quite consistent. Your bald assertion amounts to "I choose to interpret this statement in this non-standard way so as to criticise the logic which is only flawed by my invalid interpretation".

x^2 = 4. You're saying that -2 is not a solution? Just trying to understand where you're coming from.

There is one way to explain this. But first, how familiar are you with inverse functions and trigonometric functions.
