OK, this is simple because it is supposed to be intuitive but I'm just not getting it today.(adsbygoogle = window.adsbygoogle || []).push({});

Here is an example:

Solve 3tan^2x-1=0

3tan^2x = 1

tan^2x = (1/3)

tanx = (+-)(1/sqrt(3))

//All is understood at this point. It's the sentence coming up.

Because tan x has a period of pi, first find all solutions in the interval [0, pi). These are x = pi/6 and x = 5pi/6.

Ok, I understand the algebra part. But I don't get where the intuitively got x = pi/6?? Could someone explain as my book skips over that step. Thank you in advance.
